Orilla was the new homeworld of the Asgard after they had trapped the replicators in a time dilation field on Halla in November 2002. In June 2004, the planet was attacked by a replicator ship which was destroyed, but the the replicator blocks fell to the surface and started consuming the neutronium on the planet to make more replicators. SG-1 and a squad of XCOM troops were delivered to Orilla to stop the attack and were successful.
