On Neddra the Warlock (Rift Lore)  

Death has always been the most corrupting of arcane influences. At best, Mages who seek to master its power inevitably plunge into madness, while the worst wretches slowly succumb to the temptations of the Endless Court, becoming thralls of Regulos.

Neddra was one such Mage: a prodigy who saw death as the only depth left unconquered in the arcane world. For her studies, Neddra was cast out of Quicksilver College, branded a heretic and follower of Regulos. Undeterred, she journeyed north, deep into those ancient lands of Mathosia where the corruption of the Shade still held sway.

What Neddra discovered on her journey remains a mystery, but none will deny the power she obtained. For years, she waged war against the Endless Court, rooting out and destroying their hidden cells within the colleges of magic. many young Mages followed in Neddra's footsteps. These disciples, known as Warlocks, believe that only those who master death can banish the darkness from Telara.
