Technox

Ikit Claw held the warlocks of the Technox as being as close to indispensable as it was possible for skaven to be. This was to say they weren't sufficiently clever as to pose a direct threat to their master, nor were they stupid enough to inadvertently imperil his goals. Each bore Warp-powered equipment of Claw's design, complete with suicide switches that only the Chief Warlock knew. Furthermore, for that mission, each had only been granted a small but powerful warpbomb. No member of the Technox was aware of these devices' true power or instability, for Claw had gone to great lengths to conceal that information from them.
