Nihilum, never ones to rest on their laurels, tore through Tempest Keep and claimed the head of Kael'thas Sunstrider in a bold sweep that landed them the world first kill on live servers. From there, they finished the Mt. Hyjal attunement quest, and then proceeded to peek their heads in and see what was up in Hyjal. Just to send a warning shot to the other bosses that it was just a matter of time, they decided to tear Rage Winterchill a new one and leave his corpse behind as a warning. Due to a bug in that fight, Tigole had to get involved and reimburse them as only one of the items for Black Temple attunement dropped -- as opposed to the 25 expected.
With those items in hand, they headed towards the Black Temple, finished up the attunement chain, and then took down both High Warlord Naj'entus and Supremus in a one-two punch based on their hard work learning the strategies on the PTRs. In one evening, they secured four World First kills on live servers, thereby proving their dedication to the destruction of endgame content.
