"The least successful of all Slayers; these warriors have thrown themselves into deadly combat countless times and somehow survived."
- —Description of the Brotherhood of Grimnir in Total War: Warhammer III.[3]

A Doomseeker of the Brotherhood of Grimnir as depicted in Total War: Warhammer III.[3]
The Brotherhood of Grimnir is a Dwarf organisation of the Karaz Ankor dedicated to the Ancestor God Grimnir that is comprised of the most dedicated of all Dwarf Slayers. They are often the most experienced (and therefore ironically unsuccessful) of their kinsmen. The fierce warriors of the Brotherhood of Grimnir have thrown themselves into deadly combat countless times and somehow survived.[2a][3]
Wargear[]
The bands of the Brotherhood of Grimnir are composed of ten to thirty Slayers known as "Brothers of Grimnir," armed with either dual weapons or a two-handed greatweapon[1a] and covered in protective tattoos that ward away enemy magic.[1b]
At least one member of every band of the Brotherhood is a Giant Slayer who acts as the band's leader. One of the Brothers of Grimnir can be a musician, and another a standard bearer. Brotherhoods of Grimnir may carry Khazalid runic standards into battle.[1a]
