[@Calle] Yeah, the main characters have all been summoned from a regular world like ours, so they would need to be human.

Depending on the level of interest, I might be open to one of our players playing a character who is actually from Mytheria and they would have more options on the race of their character. But ideally, we need a party of regular summoned humans from a normal planet earth, and by virtue of The Summoning, have abilities and powers that could be developed enough for them to save Mytheria.
