Imperial Admiral

Imperial Admiral is a Covenant Sangheili (Elite) rank. They command large fleets. This rank does not appear in any games; it only appears in Ghosts of Onyx. Even so, the only one who ever appears is a tall Sangheili named Xytan 'Jar Wattinree. Not much is known about this rank.

Rank
An Imperial Admiral operates on a high ranking Covenant Flagship such as an Assault Carrier, Supercarrier, or other very powerful capital ships within the Covenant armada. They seem to be higher ranked than a Zealot, as Xytan 'Jar Wattinree promoted Voro Nar 'Mantakree, but this is not known for sure. It is revealed in Halo: Ghosts of Onyx that the Imperial Admiral controls the entire fleet of the Covenant. Little else is known about the rank other than that. It has been featured in one book, so little information can be given.

Appearence
Their armour is silver armor covered with the gold Forerunner glyphs of sacred mystery, Such silver-and-gold Elite armor has yet to be seen or mentioned elsewhere, and is superior in quality to the gold armor of a Zealot. Xytan travels with a large hologram of himself, and it is unknown if other Imperial Admirals do so, or if this is just something he has a habit of doing. They wear a headress for ceremonial purposes, like a Sangheili Councilor. Xytan also wears a pear of large platform boots, though it is hard to tell if all Imperial Admirals have this, as he is the only one.
