Stolas
Stolas was an Epistolary of the Blood Angels Chapter, serving with the 4th Company.[1]
Stolas was part of a 4th Company task force led by Chief Librarian Mephiston sent to the Supplicium System in response to a distress call sent by General Spira of the Mordian Iron Guard. Arriving at Supplicium Secundus, the Blood Angels found that almost the entire population of the planet, along with the Mordians, had been corrupted by a rage-plague that led to them slaughtering each other.[1]
The Space Marines then received another distress call, this time from the other inhabited planet of the system, Supplicium Tertius, revealing that the plague had spread there as well. As they made their way to the other planet, they encountered the shadow of a lost Blood Angels Battle Barge known as the Eclipse of Hope. This warp-corrupted vessel was the source of the madness afflicting the system and the Blood Angels were forced to board it, as it was unaffected by their Strike Cruiser's weapons.[1]
Mephiston himself led the boarding action, accompanied by Stolas along with Chaplain Dantalion, Sanguinary Priest Albinus, Techmarine Phenex and Sergeant Gamigin. After determining that the source of the Chaos corruption on the Eclipse of Hope was located in the ship's Librarium, the Marines made their way there, with Mephiston and Stolas entering alone to confront the warp-taint. While attempting to exorcise the Librarium, Stolas gave in to the temptation of infinite knowledge offered by the Chaos powers at work and was killed by Mephiston.[1]
