Wait this is epic. Ok, so suggestions. For powers, being able to turn people into werewolves, being able to turn into a wolf at will (maybe there's a human, werewolf, and wolf form? but the wolf form is only accessible to people with the power. maybe they start out as uncontrollable and go on hunts, but at later levels you can control them), better at fighting, greater chance to get other werewolves to do things, better at finding collectables? Maybe there can be one for controlling dogs? Or having extra skill gain at nights, "Guided by the Moon" or something? Eating raw meat and not getting sick? A weakness where if you eat anything but raw meat you get sick?
Wolves live in packs, it'd be great if there'd be new options for clubs.
I don't know if the Omega curse should be permanent- what if there's a really intricate, difficult way for them to prove themselves?
The world sounds beautiful! And I love the idea for the clothes- this whole thing sounds as I've said, EPIC. When you were describing CAS, that's just for their werewolf form, right? Like the dark form for vampires.
I don't know about traits or tattoos, so I'll leave that for someone else. For the lunar cycle, in Sims 3 it's eight days.
