Xaphen
From Warhammer 40k - Lexicanum
Xaphen was a Chaplain of the Word Bearers, who served in the 7th Company of the Serrated Sun Chapter during the Great Crusade.[1a] He was born in the Urals on Terra.[1c]
A close friend to Argel Tal[1b], when Lorgar undertook his pilgrimage into the Eye of Terror, Xaphen became one of the original Possessed Chaos Space Marines of the Gal Vorbak.[1d] Xaphen worked for Lorgar's agenda thereafter, covertly engineering the rebellion on Olympia which caused Perturabo to pledge himself to Horus.[1e]
When the remaining Gal Vorbak hunted down the Custodes force attached to the 1,301st Expedition Fleet onto Isstvan V to avenge the death of Cyrene Valantion, Xaphen was killed by Sythran during the fighting.[1f]
