The Art of Creation

The valleys of the dead were, unexpectedly, filled with the dead. As Arthur roamed about, the groups of skeletons grew larger, more organized, and stronger. These signs were bad ones that Arthur knew could only mean one thing.

There was an undead overlording these minions. 

He stopped going deeper and kept hunting the groups that were sent his way. His level rose and so did his legacy points as night switched with day twice. He had spent a whole day in the valleys of the dead, fighting moving bones that turned more bizarre the more he encountered. 

There was this one time where he encountered a bear that had fused with another, forming a monster with the lower torso of a bear before branching into two upper torsos, like a tree.
