Precursor Slaver-Nobles were the ruling caste of Taychend and Andeios during the Precursor Empire. Prideful to a fault – described often as megalomaniacal – the Slaver-Nobles are responsible for most of the monumental Precursor ruins in Taychend. They kept vast numbers of elves in bondage, housing them in winding slave-warrens below-ground through a system of indentured servitude known to the Precursors as Time-Slavery.
The Slaver-Nobles were given considerable autonomy, and Andeios was ruled as a vassal by the Precursors, though the exact specifics of this arrangement – and how the Slaver-Nobles ruled themselves, is not known. The centre of their power was in Nanru Nakar – then called Aercel – the greatest, and perhaps the only true city in Pre-Ruin Taychend. The city served as the main “docking” point for Tacenie - with the labyrinthine underground holding expansive stores used to hold tribute and supplies for the Andeios' assigned flying city - and as a testament to the power of the Slaver-Nobles in comparison to the Imperial Precursors, the high towers of the city theorised to be a mocking imitation of Tacenie's position in the sky.
Most Slaver-Nobles perished in the chaos after the Day of Ashen Skies, killed by their own slaves. Those who survived, using their magical power and control over their pre-existing holdings, became among the first warlords and the first relic-lords. Despite Ebenanth, the First Emperor, being the son of the Slaver-Noble Ulrathikeyan Starshear, it is clear that most surviving slaver-nobles, and those immediately descended from them, nonetheless perished during his campaigns of conquest. The slaver-nobles subsequently faded into myth, with many of the most prominent after the Ruin becoming deified as God-Heroes.
There are groups who claim to be descended from Slaver-Nobles – among the most well-known are the Cennayakuta of Imarchend, who claim direct descent from some of the only Slaver-Nobles to survive Ebenanth’s conquests, ruling from their ancestral, now-ruined seats of power. The Cennayakuta are infamous for consorting with infernal beings, apparently through the inherited contacts left over by the Slaver-Nobles. However, it is unknown to what extent the Slaver-Nobles experimented with infernal forces as a whole, with some theories localising this to the nobles along the Gopatri.
