Ogruna was an industrialized civilization of orcs found in Eidyn. Made up of several smaller clans, Ogruna's people lived suspended above Subterra, from whence various varieties of monster would emerge often, disturbed by their activities - the people of Ogruna contended with these monsters often, and developed their military around fighting them.
Following the Demon Wars, Ogruna awakened an Arbiter named General Lucien, who wielded the power of the Worldstone, the Leirian Aard'Vorn against them. The Ogruna were assisted by the Freelancer, a mysterious entity hailing from Kronen. Ogruna later had positive foreign relations and trade with Kronen.
