|~ Warden Eternal|
Warden Eternal is the tertiary antagonist in Halo 5: Guardians, voiced by Dan Donohue. He is a Forerunner Promethean AI, who is the keeper of the Domain, and its secrets. He serves Cortana and addresses her as the Warden's master. He has the power to posses/control bodies. In one of the cutscenes, he's been able to control over 20+ bodies at one time, for what the players of Halo 5 have seen. He is usually found in the campaign, and as a Legendary boss in Warzone; a Halo 5 playlist. After the last mission, he hasn't appeared since the final mission of Halo 5. The Warden is made out of all metal and orange illuminations, which shows he's part of the Prometheans. In battle, he usually appears with a few Promethean Knights, Soldiers, and Crawlers. His weak spot is in the back, which is the perfect place to strike him down and defeat him in battle. After UNSC Infinity went into slipspace drive, we have not seen him or his bodies since. Only the Guardian and Cortana was seen, no Prometheans, no Warden.
