Ethirium
Unfortunately Toyhouse no-longer shows us comments made during submission, so they were likely assumed to be an unmarked adopt and denied. We're working on a new system to get characters added to the gallery since the comments have disappeared on us. I've manually requested their addition to the world, I'm so sorry for the inconvenience! I'll be editing the submission rules today to avoid this confusion in the future.

Joining the Discord is absolutely optional! It's just a nice place to hang out and advertise adopts or commissions. You're still absolutely welcome to submit characters and things to the world without being part of the discord.
