The jungle world of Monthax is the setting for the end of "Ghostmaker", when Gaunt and his men encounter the alien Eldar as they struggle to wipe out a Chaos infestation. The Ghosts have to co-operate once again with the Royal Volpone 50th, and with an inquisitor who had accused Brin Milo of witchcraft. They discover an ancient portal leading to one of the Eldar's craftworlds, self-sustaining cities in space, which the inquisitor, Lilith Abferquan, closes after the alien Farseer guarding the portal dies. At the end of this battle, the Ghosts lost an excellent leader, Sergeant Lerod.
