From publisher blurb:
Exilium Mission Shard: The Iron Authority
Location: Stone.
Overview
The Iron Authority is the name given to an autonomous ‘Puppets only’ enclave on the world of Stone. Occupying an city fashioned into the sides of a huge pit originally a mine working now closed over with a super-hard crystalline roof, the Iron Authority is home to all manner of Puppets and many Simulcra, and ‘Bios’ that visit are restricted to the trading areas on the upper terrace of the pit, and even then they are closely monitored. The Iron Authority is tolerated by the Fire Council due to the numbers of combat Puppets in the site and the excellence of the mining operations they control, suppling a variety of elements essential for Puppets that are hard to source elsewhere.
