Jo Bench is generally considered to be among the earliest female members of an extreme metal band.

The title The IVth Crusade has a double meaning, as it was their fourth studio album (not counting the Peel sessions), but the album title also refers to the Fourth Crusade and the capturing of Constantinople. The cover artwork is a painting from Eugène Delacroix, showing "The Entry of the Crusaders in Constantinople".

The band takes its name from a weapon in the popular tabletop strategy game Warhammer Fantasy Battle. The lyrics and artwork of their second and third album were based on Warhammer as well as its futuristic companion Warhammer 40,000, with much of the art actually being provided by the game's publisher, Games Workshop. The general theme of their lyrics is war and its consequences.
