Forbidden Power, a new expansion set for Games Workshop’s Warhammer:  Age of Sigmar tabletop miniatures game, will release on May 25, along with a new series of terrain pieces designed for use in the game called Dominion of Sigmar.

Announced earlier this year (see “More ‘Warcry’ Details, More ‘Age of Sigmar,’ Bigger ‘40,000’ Battles”), Forbidden Power continues the Shyish necroquake storyline introduced in Soul Wars, describing the Stygxx region of the realm of Shyish, known as the “Land of Forgotten Gods,” and providing rules for players who want to stage battles as part of the War for the Stormvaults.  These rules include new scenarios set in Stygxx and guidelines for using “awakened artefacts” that can grow in power from game to game.  Two new factions, the Legion of Grief and the armies of Lethis, as well as new mercenary groups that can be added to any faction, are also described.

Forbidden Power includes an 88-page book with new background materials and game rules, models and warscroll cards for four new death-themed endless spells, a “Penumbral Engine” model, and a set of tokens for use in the game.  MSRP is $90.00.

The 25th will also see the launch of the new Dominion of Sigmar line of modular miniatures terrain.  Four pieces will be included in the first wave of releases, with suggested retail prices ranging from $40.00 to $160.00 each.
