Once we hit 1000 IC posts: Anyone other than Artemis or Hera
Once we hit a certain amount of characters, I may allow a third or even fourth demigod of Zeus, Poseidon and Hades. Right now, the max on the Big Three is two demigods per cabin. Until we hit 1000 IC posts, Hades is unavailable.
Does that answer your questions?
