From Warhammer 40k - Lexicanum
Suleiman Grimm was a Lord Commander of the Dark Angels Legion and he commanded the 7th Expeditionary Fleet, during the Great Crusade.
With the Fleet's forces, Grimm cleansed Lascal of its Feral Orks infestation and brought House Orhlacc's Homeworld, Dark Haven, into a bloodless Compliance. After doing so, Grimm granted Orhlacc an Imperial Warrant Bellicose which granted the Knight House the right to seek support from the Imperium. In return, House Orhlacc allowed a third of its Knights to join the 7th Expeditionary Fleet, before it left Dark Haven.
