Grimmok Sector
From Warhammer 40k - Lexicanum
The Grimmok Sector is a sector of Imperial space.[1]
The sector contains mineral-rich worlds that belong to the Imperium and came under threat when the Sector was invaded by the T'au Empire. The Blood Angels Second Company were dispatched to defeat the Xenos and, under the leadership of Captain Donatos Aphael, the Company deployed hit and run tactics against the forces of the T'au Empire. Due to these attacks, the T'au were tricked into thinking they were fighting a much larger force and eventually, after five months of war, the Xenos were forced to retreat when they continued to suffer unsustainable losses.[1]
