ICE age

Until Simutronics had to divest themselves from the Shadow World setting for game mechanics, GemStone III was set on the planet of Kulthea using the rules for RoleMaster, a paper-and-pencil game created by Iron Crown Enterprises; thus the reference to the ICE age.

Official word of this split was given to the player community on Friday, 1 September 1995 by GameMaster.1, GM Reline, on the Genie bulletin board system.
