Estaban System

The Estaban System is an Ultima forge well whose two principal forges, Estaban III and Estaban VII, house the Titan legions Tempestor and Magna. The system comprises at least seven bodies, of which these two are the most significant.

Estaban III is the inner forge and the seat of Legio Tempestor. Estaban VII is the outer forge and the home of Legio Magna, known as the Flaming Skulls. Both forges share a single sun. Estaban VII produces Baneblades, while Tempestor engines originate from Estaban III.

The system is notable as a Mechanicus production centre distributed across two forges, in contrast to a single-forge site such as Mars. Its standing rests on the presence of two Titan legions within the same charted forge well. Unofficial summaries continue to record its Ultima parent.
