The fires of Istvaan spread unchecked, and now the Galcoran Reach burns. Word of Horus’ betrayal has reached this distant sector in the galactic north, now caught behind the Warmaster’s inexorable advance toward Terra. Ill-prepared for rebellion, the Reach erupts into chaos as warlords, forge-priests, and rogue commanders gather their strength in the Tarkath Sub-Sector, the industrial heart of the region and its last hope for resistance or domination.

Campaign Structure

Players are divided into two factions:

• Loyalists (One Individual will be selected as Supreme Commander)
• Traitors (One Individual will be selected as Supreme Commander)
• Other (One Individual will be selected as Supreme Commander)

Teams should remain balanced, so please let us know if you’re flexible on which side you’d like to play.

Each month represents a new battlefront in the Tarkath Sub-Sector of the Galcoran Reach, with:

•  A unique star system
