Auxiliary World

Auxiliary Worlds are dimensions that Rift has discovered which posses sentient beings of enough cultural advancement that they can be recruited as auxiliary forces to serve in Rift operations. Auxiliary Forces are used heavily by the Hammer Department of Rift. 
Recruiting auxiliary personnel from other worlds allows Rift to overcome the problem of fielding armies large enough to match those of their enemies. 
In return for service, Rift contracts deals with these Auxiliary Worlds to provide their people with increased agricultural and defensive knowledge and/or technology. 
Worlds of cultural advancement equal or slightly-greater than that of Home can also be used for recruiting. Such worlds are normally engaged by Rift Command for purposes of intelligence and material trading.
