Xantek
Sir Xantek is a Noble Knight of House Taranis.[1a][1b][2][3] He pilots the Blade of Mars.[1b][2][3]
Xantek is one of the few Knight pilots to have undergone and survived the Ritual of Becoming twice, after being grievously wounded by a Chaos Titan. Some, including himself, regard this as a sign of his faith - as Taranis was once pushed to the brink of death and survived, so did he.[2][3]
