Vawk Karaow
From Warhammer 40k - Lexicanum
The Vawk Karaow was a Kroot Warsphere. Unassociated with the T'au, the mercenaries aboard it were led by a Master Shaper called the Grey King, a Kroot of prodigious size. The human residents of Saltire Vex, formerly Gue'vesa of the T'au, negotiated transportation off world to escape the planet's freezing winter.[1a] However, the Warsphere was boarded by Space Marines of the Dark Angels Chapter and destroyed.[1b]
