Ontom is a state on Sanghelios.
Ontom is a very old and very wealthy state on Sanghelios. Residents are very smug and like to remind others of their "superiority". The buildings are a blend of pre-San'Shyuum and modern architecture. The Servants of the Abiding Truth have a headquarters in a Forerunner structure located in Ontom which they were allowed to keep after the formation of the Covenant, despite their views on tampering with Forerunner technology. Jul 'Mdama and Forze went to Ontom in 2553 to join the Servants in their rebellion against the Arbiter Thel 'Vadam.
