Krillion

The Krillion are a large species of demon that hail from the planet Kril. A majority of them are sworn into servitude under Kryllakos, one of the Old Ones, who saved their race from extinction. While mostly a race that, despite their malicious looks and powerful abilities, are actually peaceful, some of their number have landed in major conflicts, such as the Maelstrom War and Reborn Maelstrom War. K'ril Xarkoroth is an example.
