Adventures are often sought out, talked about with relish. The grand peaks of one's life are the adventures within, but most find out that adventures aren't really something one can plan out exactly.
Zach and Gessa are growing up.
The two each start their very first adventure, with friends and foes, lovers and evil incarnate, and all sorts of people that populate a post-apocalyptic medieval world.
Adventures aren't always enjoyable, but can be the story of a lifetime.
That is, if one can survive an adventure to completion.
Zach and Gessa become submerged in the deathly pool of evil that is necromancy and the Lich, and must fight for their lives and very souls against undeath.
