As in the base game, the players assume the role of loyal servants of the king, transformed into mice to escape the evil Vanestra. They must work together to overcome various challenges, ranging from roaches, spiders, rats, and even the castle cat.
The Heart of Glorm includes six new chapters by Jerry Hawthorne and new artwork from John Ariosa. The expansion introduces a new mouse hero named Nere, new cards and counters, and two new figures sculpted by Chad Hoverter.
As an expansion, The Heart of Glorm requires the Mice and Mystics: Sorrow and Remembrance set to play.
Mice and Mystics proved to be a surprise hit in ICv2’s recent survey of retailers and distributors (see "Four Games You May Have Missed").
