7 and 10 for hiram?

7. What is an aspect of their appearance that you like the most?

The silly little pencil moustache! It's a fundamental part of his design, it's simple, it's fun to draw, and it's very gender to me personally.

10. What is their main character arc in the story? Where do they start and how do they develop? Do they get a happy ending or is their story a tragic one?

(I wrote a bit about his earlier characterisation here, sharing the link to avoid making this post super long)

Hiram's main arc develops through his ambition and his attempts to save London. The ambition began from a need to have more time to figure out the Neath, and it became a gamble to secure the city's future. His curious nature is what plunged him into a corruption arc after the Fall, and what's fuelling his need to always strive for more, have more, achieve more. But none of this is possible if the eldritch powers that be declare his home and his existence illegal, and he's not planning to stick around just to witness everything drown in ammonia and melancholy in an unspecified future.

Currently, he's working with Hell to forge a Law that will raise London to the Surface again (as per the ending of the Season of Skies), indirectly supporting all revolutionary endeavours as a plan B, although he'd rather control the Laws than dismantle them completely. Just in case, he's also fomenting as much chaos as possible on a certain chessboard.

His plans will ultimately fail because he's slowly becoming increasingly obsessed with power and control, not trusting anyone other than himself to see the bigger picture. His goals are good, but his problem solving skills are just like him, too uncaring and self centred to achieve anything useful.

He'll really start to improve and let go of some of his ego after the fall of the 6th city, but not fast enough to prevent the fall of the 7th. He won't ever become a morally good or law abiding person, but he'll tone down the unhingedness, slowly realising that the ends cannot always justify the means. He'll end up finally saving Berlin in the Neon Future, one way on another. The headcanon is always a work in progress, it changes as new developments are introduced in game, and I consider the Neon Future to be an open ending for his arc.

Hiram is a fun oc, and he has a lot of silly moments, but he's fundamentally a tragic character. No matter how much he tries to control his own narrative, he's always in the throes of his desires, and things will have to get even harder for him to understand that he needs to change and improve his attitude in order to change and improve his surroundings. But he'll end up reluctantly dragged in a found family trope in the Neon Future, and the whole narrative genre will shift from tragedy to sitcom so yes, there's definitely a happy ending, albeit bittersweet (it includes Morgan's true death, amongst other things. @thunder-threnodies and me have a lot of future headcanons that we might or might not share sooner or later)
