#so honestly you could get away with having the secondary chb only having a few extra cabins compared to the 12 usual cabins

my notifs recently got me thinking about the very random concept of "what if there is a second, secret CHB. directly below normal CHB." and i ended up brainstorming it in the discord.

context for how this originated: one was just a random notif on my post talking about the tunnels under the Hephaestus cabin, and the other was some tags from @drksanctuary on my fake readriordan article mentioning the idea of a chthonic demigod camp.

so. my brilliant (read: "smashing my 2 brain cells together") idea: the elaborate and seemingly infinite tunnels under cabin 9 are remnants of an abandoned underground CHB that exists directly underneath camp. It's basically just normal CHB except in a big cave system, probably connected to the labyrinth somewhere and has the separate tunnels, and instead of the Olympian cabins it has chthonic cabins. there's probably also some infernal nymphs and etc down there too. since all chthonic demigods can learn to shadow-travel they probably used that to get down there, and a lot of chthonic demigods probably have geokinesis just by nature, ergo the tunnels (for when they don't want to shadow-travel, or can't).

in brainstorming with the discord we decided it could be cool if some of the cabins lined up with the above-ground cabins, either for thematic purposes or associations or whatever. Like there's maybe a Hermes and maybe Poseidon cabin in the chthonic CHB too that just link to the above-ground ones, but also like Persephone cabin lines up to Demeter cabin because of course it does. and maybe Hecate cabin lines up to Cabin 8 cause Artemis is sometimes 1/3rd of Hecate. Maybe Angelos cabin is beneath Cabin 1, and Zagreus cabin is beneath Cabin 12. Things like that.

The other ones i thought of were either Hypnos or Thanatos cabin lines up with Apollo, because twins, and the other is just right beside it (because twins). And Charon's cabin is beneath Cabin 9, ergo why the tunnel system connects to it (because Charon. Ferryman. Surface access. It makes sense in my brain).
