The Labyrinth hungers once more.
Or is it all just a sign of madness?

A great number of skills for characters to learn and discover, then teach further to other characters.
Explore different environments, investigate mysterious objects and artifacts, and meet some of the friendly natives of the Labyrinth.
A number of difficulty modifiers to amp up or down the difficulty.
