idk if this is accurate but i’ve felt like in previous seasons riz & gorgug have been one of the inter-bad kids dynamics we’ve seen the least of & this season has been so great in that aspect. gorgug having helped make some of riz’s magic gear. riz helping gorgug with his studies. the shared birthday party. gorgug’s gift to riz being something he himself made to protect riz. riz’s gift to gorgug being something he illegally grabbed to protect gorgug. gorgug who utilizes rage to put his body on the line for his friends & riz who will take deep levels of mental stress for his friends. even though it was within the context of a joke, riz calling gorgug an “absolute sweetie.” like yea they might not be in a band together or both part of a presidential campaign team or owlbears teammates, but they’d go to war for each other, because they’re best friends.

Disabled Aelwyn who uses crutches.

Aelwyn who can’t go back to school to finish her wizzard studies, who starts researching different ways to bend magic to her will.

Aelwyn, who has always had a knack for creating new spells, starting to tinker at her own crutches, weaving wards into the framework.

Aelwyn, for who good is not good enough, caves and asks Gorgug for help. Who finds a way to make her crutches extend, bend and move to support her arms, elbows, shoulders. Makes them connect to her back, her hips, down her legs .

They no longer look much like crutches anymore, it’s a thin, light framework that supports her entire body, that moves her exactly the way she wants, that allows her to stand with her back straight for more than 5 minutes for the first time in two years. The exoskeleton glows with abjurative runes and the outline of a powerfull ward is visible over her body, deflecting blows like steel armor.

New spells rest in her memory, mechanical and precise if nature in a way that the arcane inks in her spelbook can’t articulate. Spare the Dying, Resistance, Cure Wounds, Sanctuary.

Her joints still ache, she tires fast and even after all this time it is still hard to control the venom in her words, still hard to accept help and kindness without it feeling like a wool blanket on freshly flayed skin. But she has found something that is wholly hers, found something to be proud of that isn’t tinged with approval from her parents.

Aelwyn still can’t walk without support, but the frame folding her up is crafted by her own hands. Maybe everything will be allright.

tbh i think that even unwinnable fights should be winnable. some of the BEST fights i've ever run as a dm were ones i built kill the players (in a fun way. I had some cutscenes prepped so even the loss would be a different flavour of win)- but then they were clever bastards and managed to either win the fights or pull themselves out of trouble. I think it's perfectly fine to plan for a fight that players aren't supposed to win, but you need to let them. if they can't win, they can't lose, and the meaning of that encounter is diminished. do that too many times, and they stop trusting you to give them roleplay prompts and start expecting to sit there waiting while you drive the story for them.

but if they can win... if there is always the chance to win, no matter how impossible the odds, then they ALWAYS have hope. they always get invested. they feel the big emotions of success or the big emotions of failure, and you fucking Win as a dm/roleplay prompter/lead bastard.

"Your trauma made you stronger"

Actually my trauma nearly destroyed me.

It gave me nightmares and stole my voice,

it gave me destructive coping mechanisms

and made me feel deeply unloved.

It took my own strength to face my trauma

and tell it that it will not win

I was handed a terrible situation

that was not my fault and I learned

how to survive despite my trauma

therapy isn't enough i need to uproot some fucking pine trees toss them off the cliff come home slam seven doors and hole up in my room is it too much to ask??

Brian: God give me patience.

Ivy: You mean “strength.”

Brian: If God gave me strength I’d have tossed you all into a black hole a long time ago.

We respect brian for that, i'd do the same if my arms werent spaghetti

Bad News

Villain knew Hero could see them through the wall, so when they grabbed the trash can from the street and threw it in their direction, they expected the hero to duck. When they peeked around the corner, they looked up just in time to see the metal container miss the hero by a concerningly-small margin. Hero just stood still, like they hadn’t even noticed how close they had just come to decapitation by dumpster.

Villain was dumbfounded by the hero’s careless behavior right in the middle of a fight.

“I could’ve seriously taken your head off!” Villain yelled, but their anger subsided when they saw the look on their enemies face.

Eyebrows pinched, mouth downturned, and eyes distant.

Distress, plain and simple was written all over their features.

Their suspicions were confirmed when they were able to successfully rush and grab hold of the hero, crossing their arms across their chest and preventing their escape. The hero squirmed, but they could do nothing caged tightly in the villain’s arms.

“What’s on your mind?” The villain inquired to their new, confusingly-distracted hostage.

“It’s nothing,” Hero deflected.

“It’s not,” Villain challenged, loosening their grip so that it wasn’t so harsh. When the hero flinched, Villain shifted to a gentler tone.

“It doesn’t take x-ray vision to see your heart isn’t in this right now.”

Reluctantly, Hero admitted, “I got some news, okay?”

“What kind of news?”

“Not good.”

The hero with enhanced vision turned their head and huffed.

Carefully, Villain asked, “How bad?”

“Not sure yet,” Hero sighed, going quiet for a moment before snapping, “Its always one thing after another. It never fucking stops, it’s just shit on top of an already heaping pile of shit-“

They cut off with a choke. When Villain looked down, they saw tears welled in their eyes.

“I just don’t know how to deal with it all. It’s just…too much.”

Hero sagged, and Villain’s restraining hold turned into something more reminiscent of a hug.

“Hey, I may seem like the strong one here, but if we measure in anything other than bone-crushing-abilities I think you’d have me beat.”

A moment passed in silence. Around them, the city buzzed. Cars passing, drivers honking, lights changing, life continuing. To Hero, the world shrunk. It was only the gentle breeze of their own breath passing through their lips, the rise and fall of their chest beneath the Villain’s arms.

“I don’t want to be strong,” they finally whispered.

“I know,” Villain hushed, “I’m sorry you have to be.”

Hero laughed weakly in an attempt to lighten the mood, “Since when does my nemesis apologize?”

Villain allowed the abrupt shift, responding easily, “Since you started getting all sad I guess.”

Hero chuckled lightly in their arms, then sniffed.

“It’s okay to take a break, you know.”

Hero used their freshly released arm to wipe their sleeve across their nose.

“Nah, I’m right where I want to be. Plus, who else is gonna beat your ass if I’m gone?”

“Sad and delusional I’m afraid,” the super-strong criminal replied.

Villain stepped back, and the hero turned to face them.

“Thanks,” Hero offered awkwardly. They shifted on their feet, unsure of where to go from here.

Villain simply nodded, walking backwards across the concrete until the hero broke eye contact.

“Don’t mention it,” they called as they turned and left. The hero didn’t stop them as they cleared the crosswalk and disappeared.

I don't get why people hate the timeline so much, its not like you can't pretty much completely ignore it when you play the games. The only time it even approaches mattering to the story is when there is an explicit sequel like botw and totk or zelda and zelda 2

Hey sorry your ask got lost in the sauce of my broken tumblr, but: yeah!

I mean, I get why in some sense. It's been a heated point of debate and I think some people understandably resent the space it has taken not only in fandom discourse, but in how people began to understand the game and its narrative aesthetic choices. There is such a thing as over-rationalizing everything to hard logic, and sometimes it's just not the fandom for that --especially when you begin to forget it's all just fan theory and start to forget what the games are supposed to be like and evoke beyond just strict facts displayed in a linear way.

What I think bugs me with TotK in particular is that it both evokes and relies on continuity and the idea of a timeline, of archeology, of history itself, while being so loose and vacant with it that it both is doing Timeline Shit while also completely failing to understand why some parts of the fandom were invested in Timeline Shit to begin with.

But that's just my two cents of course!

pondering on a meta diving into Gale's abstract brand of selflessness (willingness to go away to a corner of the world to die so that none of the faceless masses will be harmed by his mistake) vs his personal selfishness (willingness to stick by tav despite being repulsed by tiefling camp murder + general vocal approval or interest in accumulating more power) and Gale's status as someone who is good aligned but generally ineffectual at enforcing actual good (the way that wyll or karlach will actually leave the party) which is fascinating for a fairly good-aligned person. just love when the Good Guy is actually kind of fucking weird. edit: tumblr cut off my tags Okay. and how all of this ties back in an interesting way to his relationship and power imbalance with mystra. he was wronged, deeply, but he also desires still that ... status / closeness to divinity in some way, by her influence. Gale thinks that he would be a better god simply by virtue of his mortality but he cannot escape the appeal of holding himself apart from others and being more than, greater than, something closer to godliness and thus inherently removed from mortal values and standards of right and wrong, which the gods themselves don't adhere to in the same way.

Ollie's an absolute heartthrob. Especially with the short hair. And super built, I am swooning! She popular in Hell?

oh there were a few moments in the beginning where she had to fend off Val's offers for a job. Unfortunately for him, Ollie is a homebody who stays in her workshop, and has her maid/assistant Thea do her outside errands.

(I'm thinking despite her appearance Ollie is actually a very gifted technomancer/artificer. She can fix or create just about anything with enough time. which is how Alastor and her meet at first!

someone's gotta fix his microphone after all!)

Ollie's actually very intimidating to most demons, just from her size and build. But yeah she is verrrry popular, especially with the ladies lol.
