From Warhammer 40k - Lexicanum
Astramael is a famed Furioso Dreadnought of the Blood Angels.
He is most notable for leading the Chapter's full strength of forty-one Furiosos against Ork forces assaulting Baal under Warboss Big Skorcha in 789.M41. If it were not for the efforts of Astramael and his Dreadnoughts, Baal's Fortress-Monastery would have fallen to the Greenskins.
