- Everyone knows that spells are alive, and sometimes become conscious. What is less well known is that sometimes a conscious spell merges with the spellcaster, weaving its magical essence into the physical body and metaphysical mind. The final being is no longer the spellcaster nor the spell.
- On rare occasions, an undead will accidentally regrow a soul. Maybe the soul hadn't fully died off upon undeath, or maybe it's a soul cancer. In any case, it can happen. Sometimes too, a soul finds its way back to its undead body. Sometimes, an old soul and a new soul meet. Usually this leads to violent astralogical conflict that leads to the collapse of both souls. On extremely rare occasions, the two souls reconcile, and the being is returned to life, but now as an entirely new soul.
Well, I only came up with two, but I think they're pretty good. The latter is a concept I've played with on this blog before, but I think the former is new for me, and I think could be expanded in some cool ways.
