The necromancer and the druid officially got together after saving the Chaos Realm with the party. Unfortunately the moment they brought down the enemy's wizard tower it sucked them into a separate Plane. An empty black void for 3.14 years.

During that time Barzele thought it best they have a child before he completed his transformation into a lich. And so they had their half-elf son, Wildolec. That kid is gonna be all kinds of special being raised by talking skeletons/animals/trees on an airship in the middle of nowhere...
