The Maccabeus Clan was a Jiralhanae clan serving in the Covenant Army. The clan fought during the Battle of Harvest, being attached to the Rapid Conversion at that time.
The clan, as their name implies, was led by Maccabeus, who was soon killed by Tartarus. Tartarus then gained control of the pack, and he later became the Chieftain of the Jiralhanae.
It was a very prominent and a well-known clan among the Jiralhanae.
