Typhus

Typhus was born Calas Typhon on the Death Guard's eventual homeworld of Barbarus. Typhon was a half-breed, the result of one of the Overlords of Barbarus taking a liking to his Human Mother. For this, his mothers fellow villagers drowned her.[19b] As a child upon the toxic planet of Barbarus, Calas Typhon was troubled by nightly phenomena over which he believed he had no control. Objects would shudder and smash around him whenever he was frightened or angered, and plants would wither and die under his gaze. These phantom powers troubled him greatly, but he resolved to turn them to his advantage. By the time Typhon reached maturity, he had learned to master the psychic energies that resonated within him each night; a feat of will that impressed his elders mightily. With this act, Typhon became stronger in his resolve to succeed than any of his peers. When Mortarion defected from the Overlords after witnessing their atrocities, Typhon was the first person the Primarch encountered and the young child helped lead him to safety.[19a] During his early adulthood, Typhus was a champion of Mortarion's early Death Guard in his war against the Warlord of Barbarus.[18] When the Emperor reclaimed his lost son Mortarion from the poisonous mists of Barbarus, and reunited him with the the superhuman warriors born from his gene-seed, Typhon was amongst those chosen to join their ranks. As he joined the legion, his psychic potential was suppressed through training due to the anti-psyker sentiment of his Primarch. Nonetheless through his rugged talent, Typhon was eventually able to rise to the prestigious position of First Captain.[12a] He shared a strong bond with Mortarion, the two being close comrades due in part to their shared origin as outsiders even among Barbarus
