So, we were going to do this at random, but a lot of people seem to like the plague idea, and there's already a lot of good points to work with. We'll keep the wanderers coming in on the back-burner for now, since it would work best when we had a few more in play. Actually, we might be able to do a round of ads specifically geared towards getting more of the wanderers in game.
A magical plague would be a great idea! If people like the "opposite talents" idea, we can brainstorm some opposites together. If people would prefer some other sort of symptoms for the plague, we can always try something else. Perhaps there's a danger of losing talents altogether if it goes unchecked for too long?
Just thinking it over, we'd need some help coming up with some clever opposites for elating, moving, flying and shapeshifting, if we were to go this route. The others we have some ideas for, but you can always suggest those too, in case your ideas are better than ours ;)
And if people aren't fond of the plague idea, (and even if you are!) you don't have to make your character contract it. You can feel free to keep it to NPCs if you like.
We can make another post on this for more discussion, if people want to go ahead with this idea.
