Maral Lupus
From Warhammer 40k - Lexicanum
Maral Lupus, known as the White Wolf, was a member of the Luna Wolves during the early Great Crusade.[1]
A Praetor, Lupus led his legion during the First Pacification of Luna and subsequently became de facto Legion Master. He was killed barely a decade later while leading the final attack during the Battle of Luhman.[1]
