Inferno faction discussion.

Firstly, "succubus" doesn't decline, and as for whether they "will be" added, it's still unknown, as there's currently information only about two characters.

Why not? It does decline: no succubus, give a succubus, find a succubus, control a succubus, on a succubus. But the nominative case is indeed "succubus." Male gender, as someone came up with - incubus.

No, God forbid any fiery genies or overgrown imps! It's better to finish what they already have! For example, make the demoness more attractive, and draw a third head for the dogs!
