Pavonum

Pavonum was a Blizzard employee who worked in the Customer Service Forum until December 28, 2007. His avatar was an owlbeast native to the Hinterlands. Pavonum was known for being verbose, using signatures from foreign languages (often Latin or French), and enjoying tea. His penchant for disassembling ill-considered arguments, as well as decimating attempts at deception with piercing facts and vicious rhetoric, inspired the term "Pavowned" for any occasion where would-be pretenders were swept away in a deluge of words, statistics, and collective disdain from regulars.

While he was known for dismissing the veracity of hearsay — he often quipped, "They say rumour flies, but it rarely flies straight," when faced with unlikely claims from still more unreliable sources — Pavonum has purportedly left Blizzard Entertainment to continue his pursuit of knowledge outside the harsh realm of customer service. Though he is still thought to reside in Southern California, there are whispers that he looks northward, to the grey and misty climes of Seattle, for a career in the culinary field. His passion for literature and language remains unabated, but, professionally, the kitchen's cramped, sweltering heat and wafting aromas call to him. No fried Moonkin will appear on his menu.

Legend has it that Pavonum, for some time after leaving his official capacity on the Customer Service Forum, posted sporadically on his play account as Umbrae of Trollbane. Perhaps surprisingly, no one noticed the similarities between the writing styles used by Pavonum and Umbrae, despite the fact that he made almost no effort to disguise his unique brand of eloquence.
