Khrove
Khrove is a Sorcerer Lord and warlord of the Thousand Sons. Unlike many of his Chaos Space Marine colleagues, Khrove was not an original member of the Legio Astartes or a veteran of the Horus Heresy. Rather, he worked as a scholar on the Imperial world of Prekae Magna at the start of the 41st Millennium, studying and interpreting Imperial holy scriptures. When a collection of heretical tracts fell into his hands, Khrove collected much rare and arcane knowledge, leading him to be kidnapped by Ahriman and inducted into the Prodigal Sons as an asset. When a rival Thousand Sons warband crossed paths with the Prodigal Sons, Khrove was captured and returned to Sortiarius where he continued working his trade. Khrove proved to be adept and powerful enough that he was worthy of being inducted into the Thousand Sons after surviving brutal training and genetic enhancement. Khrove eventually formed his own warband.[1]
Khrove was among the few who accepted the invitation by Iron Warrior Dreadnought and Chaos Lord Chengrel to win possession of captured Eldar Spirit Stones, won by whoever could impress Chengrel the most by recanting a tale of destruction against the Imperium and offering a substantial bid. When Khrove's turn came up to relay a tale, he told of his personal origin and the brutal and bizarre training he underwent to become a member of the Thousand Sons. However, Chengrel became irate and unimpressed with his guests, to the point of not bothering to allow Emmesh-Aiye offer a bid after relaying his tale nor letting Khrove even finish with his own story. Chengrel's displeasure only increased after learning that their histories didn't stretch back to the original Horus Heresy, and their implicit "impurity". When Khrove personally challenged Chengrel on his own accomplishments, pointing out that he hadn't even attained the rank of Warsmith, Chengrel flew into a fury and attacked his guests, swiftly resulting in a free-for-all battle for control of the stones.
Khrove, armed with his sorcerous powers and defenses, battled Chengrel to a lengthy standstill until he turned Chengrel's forward legs to crystal, which immediately buckled and disabled the Dreadnought. Emmesh-Aiye had at this point seized possession of the spirit stones, and Khrove confronted and swiftly killed him with his powerful sorcery. After finally capturing the stones, Khrove dismantled his lander (which was a decoy), and teleported back to his ship. Since then, the Iron Warriors warlord has vowed his vengeance against the marines who betrayed him rather than against the Golden Throne, something that Khrove would be amused by if he ever learned of it, and would quickly point out the irony if they ever met again.[1]
