"Everything is blood, Sarpedon! Ourselves, the enemy, you, me, the earth, the stars! And when you realize everything is blood, you know that blood only flows one way! Blood, Sarpedon! Blood for the Blood God!"
- — Tellos of the Soul Drinkers
Sergeant Tellos led his Assault Squad during the Soul Drinkers' attack on the Van Skorvold Star Fort of the Adeptus Mechanicus. Under Librarian Sarpedon's command, he fought through the star fort to retrieve the artefact of the Chapter known as the Soulspear, but it was stolen right in front of Sarpedon by the Tech-Guard of the Mechanicus, which wanted the artefact for itself for study.
When the Soul Drinkers attacked the Mechanicus platform to reclaim the aretefact from the duplicitous Mechanicus adepts, Tellos was seriously wounded after both hands were wrenched off at the wrist by an Adeptus Mechanicus Electro-priest.
His life was saved by the Soul Drinkers' Apothecary Pallas who dragged him to safety. Whilst recovering on the Soul Drinkers starship Gundog, Tellos was found to be jamming metal shafts into his amputated stubs and destroying servitors at random in the ship's Librarium.
Tellos had the most obvious Chaotic mutations in the Chapter, second only to those of the Chapter Master Sarpedon. Refusing to accept any other fate, he always wanted to fight on no matter the odds; he had chainblades grafted into each end of his arms whilst his accelerated healing mutation held them in place and allowed him to regenerate almost any damage he took instantaneously. His second mutation was a grossly enhanced muscular system and semi-translucent skin.
During the time Sarpedon was looking for a cure to halt the Soul Drinkers' rampant Chaos-induced mutations, Tellos disobeyed Sarpedon on numerous occasions.
When the cure was finally located, the Soul Drinkers were forced to abandon Tellos and forty Assault Marines on Stratix Luminae. They were last seen taking on tens of thousands of mutants and undead creatures from the Chaos Lord Teturact's heretical army.
A few standard years later Sarpedon received word that Tellos and his Assault Marines had wiped Stratix Luminae clean of life, and had openly pledged his loyalty to Khorne, the Chaos God of blood and war.
Tellos was eventually tracked to Entymion IV where he and Sarpedon engaged in a final duel over a bridge. Sarpedon was barely victorious, but during the battle the bridge collapsed, burying Tellos in rubble.
Tellos survived Sarpedon's assault and sat amidst the ruins of the bridge where he had fought the Soul Drinkers' Chapter Master as Cyclonic Torpedoes intended to carry out the Exterminatus bored into the surface of Entymion IV and ignited the world's core.
His final thought was "More blood for the Blood God," as the planet broke apart beneath his feet.
