Arcadia is a Forge World of the Adeptus Mechanicus. Due to conditions of the surface that are hazardous to human life, its entire production facilities and population exist underground. Arcadia was given the STC to produce Leman Russ variant turrets after the destruction of the Gryphon IV Forge World by the tryranids. It is also a major source of small arms in the Expanse.
