I was playing around with a few different ideas but the one I settled with was basically crystal gets kidnapped by a monster so Nico, Blake, and Will go on a quest to save her. Along the way the battle lots of monsters and Blake gets injured and Will stays behind to heal him while nico continues along over using his power he just barely manages to get the four of them back to camp before he melts into shadows. I was going to write a sequel to it after the bad ending but never really got around to planning much
