Olecs

 Lithidarian for "undead", Olecs are among the oldest forms of unnatural races in Metas' history and even predate the reappearance of Tocaderg, who many mistakenly believe to have introduced them to the world. Necromancy has existed since the Cosisians of the Southern Kingdom first discovered magic during the Age of Consolidation. Before the Koll corruption of the necromancy arts, it existed as a weak and primitive form of void and mind magic, using it to return consciousness to dead relatives only for a short time. It's use among the Corisians was mostly harmless and wasn't able to produce anything worthwhile for use, good or ill. Once Tocaderg appeared as a Prophet of Destruction, the Olecs became much more dangerous as millions of bodies were stolen from graveyards and battlefields to add to Tocaderg's ever growing army of undead.

All natural races are capable of being resurrected into Olec form, some being more dangerous than others. Most are slower than their living counterparts, but far more durable as even lost limbs won't stop an Olec onslaught. Other Olecs retain special abilities that their former living selves had access to. Olecs are difficult to completely subdue as severing limbs result in a new, pure energy limb replacing it thanks to the Koll-boosted necromancy. The only way to truly stop an Olec is to sever the head from the torso. One thing among all Olecs remains true in almost any combat situation; they always outnumber their living counterparts, especially those fighting against them.
