Thanassar
From Warhammer 40k - Lexicanum
Thanassar was an Adeptus Custodes who was considered to be among the greatest of their numbers and was noted for being one of the few Custodes capable of dreaming. He had the accounts of his dreams written reverently to script and they are buried in the deepest vaults of the Imperial Palace's Inner Palace, along with the recorded dreams of other Custodes.[1]
