Bel'shir gliders are large, floating whale-like creatures native to Bel'shir. They contain terrazine in their bodies, which is able to be extracted from them through use of an extraction device.
During the End War, Amon's Forces attacked Bel'shir, and began to extract terrazine from two Bel'shir gliders. Egon Stetmann requested that the allied commandeers helping him with his terrazine harvesting operation freed the gliders.
Stetmann mentioned that he did not remember seeing them on Bel'shir before recently.
