Moredakka

Moredakka is an Ork World that is infested by Orks of the Deathskulls Klan. Formerly known as Mordax, this former Forge World of the Adeptus Mechanicus was captured during the 13th Black Crusade massed warbands of Orks during their so-called 'Green Kroosade', which has ravaged the worlds of the Scarus Sector.

History
When the Forces of Chaos launched the 13th Black Crusade, Abaddon the Despoiler recruited massed warbands of Orks to act as mercenary auxilias to his Chaos Legions. Following up on terror raids and cunning feints by the Night Lords and Alpha Legion many of the Orks banded together into ever-growing tribes that declared themselves as part of the "Green Krusade" (or Kroosade in other sources) in imitation of the grand assault of Chaos. The Green Krusade inundated the Scarus Sector, battering down Imperial defences with a little help from Chaos Space Marines, particularly of the Night Lords and Black Legion. Now the Orks rule multiple worlds, including the weapon forges of Mordrax, (rechristened 'Moredakka' by the Orks), whose weapon forges are infested with lootas of the Deathskulls clan, a truly terrifying prospect to the devotees of the Machine God, who know full well the depths of blasphemy against the Omnissiah to which these barbaric xenos will sink. Battered survivors speak of hundreds of Gargants are being built from the debris of war by enslaved Servitors and their brutal Greenskin overseers. The squat, menacing forms of more Gargant construction sites climb over the plains of Mordax daily as Ork Mekboyz race to be the first to complete their machines. Imperial strategists are now regarding the Green Kroosade as a full-scale Ork WAAAGH! Its Warlords are unknown but it would appear that Ghazghkull and Nazdreg are not among them.
