Estaban System

The Estaban System is an Ultima forge well with at least seven rocks, two of them important: Estaban III, inner forge and seat of Legio Tempestor, and Estaban VII, outer forge and home of Legio Magna the Flaming Skulls. Twin forges sharing one sun is the point.

Baneblades leave VII; Tempestor engines leave III. The system is a Mechanicus battery, not a single-forge shrine like Mars.

The Estaban System still matters because two Titan legions bill from the same charted well. Unofficial summaries keep the Ultima parent.
