Cursed isn't an ability, it's something that happens during the game. It can't be modded, and no creature starts with it AFAIK.

That sucks. I can think of plenty of units, commanders, pretenders starting with curses, or horror marks. Some tartarians, various warlocks and renegade wizards dabbling in forbidden magicks, pretenders cursed in past millenia, and heroes of course. It would add a lot of flavour.
If it's possible for an unit to start with affliction, why disallow curses and horror marks ? Curses and marks make even more sense, because they can't be removed, so they're essentially like stats.
