Nigon is the second underground race.

The majority of the heroes will be Illithids)) because they are the most intelligent and numerous race, and they also have limbs, unlike beholders))) and of course, there will be a couple of humans) and maybe one Ifrit)
in principle, you can find some kind of underground creature and put a hero on it)) but it definitely won't be from a castle) I don't think it's worth making the hero a foot soldier) they are not very big in size))) clothing: a cloak, a mantle, etc.) I haven't decided on the face yet) it would look strange for a human hero to have an Illithid face in battle))) you can cover the face with something).
