For some general consideration take a look at this previous post, the details below are about the expansion for Dungeon Saga called: The Tyrant of Halpi.
These are the minis in the box:
Karrathor The Unbroken : aka The chubby Dragon (which is going to be used in a bunch of other Mantic Games products)
Ibrahim, Human Paladin (one of the new heroes)
Ally, Halfling Thief (the second new hero)
