Warbreed
From Warhammer 40k - Lexicanum
The Warbreed was the personal Battle Barge of Warsmith Honsou, controlled by Etolph Cycerin through a specialized tank of bio-conductive gels stolen from a destroyed titan, combined with technology stripped from the Basilica Dominastus.[1a]
Honsou used the Warbreed at the Skull Harvest within the Maelstrom[2], as well as in the attacks on Talassar and Calth during the Bloodborn's Invasion of Ultramar.[1a][1b]
It is unknown if Warbreed survived the battles of Ultramar, although a single vessel did escape the Ultramarine fleet[1x] and this could have been Warbreed.
