Hesduros

Hesduros is a Sangheili colony world.

History
Then known as Kelekos, the planet was once part of the Forerunner ecumene. The Forerunners left at least one portal device on the planet, which was synchronized with Shield World 006. A nearby building was engraved with the coordinates of the shield world Requiem as well as a warning not to disturb the Didact.

In March 2553, Shipmaster Jul 'Mdama escaped ONI captivity on Shield World 006, now known as Trevelyan. The portal through which he escaped made him emerge on Hesduros near Panom Keep, from what the residents called a "holy gate". The locals had been out of contact with the Covenant for about a year and were thus unaware of the Great Schism. Exploiting their religious devotion to the Forerunners, 'Mdama convinced Panom to join his cause, beginning the formation of a powerful militant resurgence of the Covenant.
