Estaban III

Estaban III is the inner forge of the Estaban System and the seat of Legio Tempestor, the Stormlords. In the Heresy a Tzeentch-leaning machine-cult there sided with traitor Tempestus elements and fed Horus engines for Terra; loyalist Blackshields later took the world back. Iron Hands and Tempestor Titans had to save it again from Chaos in 751.M41, so the sister-forge next door is not this pin's whole story.
