From the introduction: This replaces the following Supplements: Warehouse, Housing System, Companion Housing Complex, and The Bay. It is not compatible with any of the alternatives that replace one of these, for example Fortress of Jumper, but is compatible with all Warehouse modification options that can be found in various jumps, and fully integrates with the Biosphere Supplement from the Fountain. Universal Drawbacks Supplement (UDS) Notes: There are a small number of drawbacks in the UDS that grant Warehouse Points if you make them Chain-Drawbacks. The points given are those from the original 150 Warehouse Supplement created by RT / Quicksilver. They may be applied to this Supplement as well by multiplying them by a factor of 10. Certain elements were copied or adapted from original documents; all credit to their original authors.
