Ashenfangs: Ashfall is a grimdark military-thriller set in the universe of Warhammer 40,000 following the Ashenfangs, a stealth-focused Raven Guard successor chapter that wages war through infiltration, psychological collapse, and surgical execution rather than open conquest.
The story centers on Nightfang, the 2nd Company, as they infiltrate Hive Tertius on the industrial world of Nethros to uncover a growing secessionist conspiracy led by House Veydrak. What begins as covert investigation evolves into a calculated campaign of assassinations, infrastructure collapse, and engineered fear designed to break the hive from within before open war ever begins.
