PDF – Pay What You Want
Supplement to Osprey Games' Castles in the Sky from the Osprey Wargaming Series 30 (OWG 30) written by Eric Farrington. This is not a stand-alone game. To make use of these rules and ships, you will need a copy of the Castles in the Sky rules to take full advantage of this PDF. The Castles in the Sky rules can be purchased wherever fine books are sold.
These rules were intended for publication in the original book, but were cut due to space reasons. Written by Eric Farrington, they were originally published on the Blood and Spectacles blog.
