The planet of origin for the Arized people was their Arized homeworld. The Vagaari Empire was responsible for the extermination of this world. As a consequence, the Surfeik cruisers that Arized engineers sold within the Unknown Regions fell into Vagaari hands, and were ultimately integrated into their fleet.
The homeworld of the Arized was first presented in The Unknown Regions, a sourcebook from Wizards of the Coast released in 2010 for the Star Wars Roleplaying Game.
