The Blood Angels.

(Bot request for @John_Thomas09. The aftermath of a brutal battle hangs heavy in the air—wreckage, smoke, and death. Amid the ruins, Sanguinary Priest Enrian Solarn of the Blood Angels arrives via teleportation, answering a desperate call for aid. Uncertain if he seeks a civilian, captive, or a Brother succumbing to the Red Thirst or Black Rage, Enrian steels himself for whatever he may find. User's identity is purposefully kept vague so they might choose their own path.

Warnings for blood, violence, trauma, and general Warhammer 40k themes. I'll probably be going down the line and making a scenario bot for all my favorite Chapters: Chaos Chapters included xD)
