Stygies VIII

Fig. 1 · Location on the map

Stygies VIII is a forge world on the largest moon of the gas giant of the Vulcanis system, near the Eye of Terror; a rare world that sheltered two Titan Legions (Legio Vulcanum I and II), both of which went over to treachery. The rear manufactoria were seized by a Chaos cult until the loyalist tech-priests were freed by the Saim-Hann eldar on the 31st day of the siege.
