Lak 'Vadamee

Lak 'Vadamee was a member of the Vadam family, rulers of the powerful State of Vadam. He was old for a Sangheili and was an Elder of the Vadam lineage. He served as an adviser to Thel 'Vadam and was the one who taught Thel how to fight and use his reasoning skills from such a young age. He is known to have a relation to the Arbiter Thel 'Vadamee as they both have the same pre-fix of their name.

When Thel returned from his mission to the 23 Librae system with a promotion to a command in the newly formed Fleet of Particular Justice, he confided in Lak that he was confused about his old beliefs about the perceived omnipotence of the San 'Shyuum and the worthlessness of the humans. This confusion was caused by the small feud between Regret and Truth indirectly causing hundreds of thousands of Covenant deaths and his close encounter with Jai. Thel was worried that his thoughts verged on being heretical. Lak reassured him that what heresy was depended on who was in power, citing the Sangheili-San 'Shyuum War as an example, before encouraging the future Arbiter to be optimistic and to triumph in his promotion.

Also, he has been know to serve in the Sangheili Military Forces as the suffix to his name is 'ee'.
