Trond Bråthen (28 May 1977 – 13 May 2012), also known by the stage names Trondr Nefas and Alastor Nefas, or simply as Nefas, was a Norwegian singer-songwriter, guitarist and bassist. Despite being primarily known for his work as the vocalist and lead guitarist of black metal group Urgehal, which he founded in 1992 alongside Thomas "Enzifer" Søberg, he had numerous other projects as well, such as Beastcraft (in which he performed as "Alastor Nefas"), In Lingua Mortua, Endezzma (formerly known as Dim Nagel) and Angst Skvadron. In all of those side projects he collaborated with fellow musician and former Ásmegin member Lars Fredrik Frøislie.
On 13 May 2012 (at age 34), Bråthen was found dead at his home. According to his Urgehal bandmates, he most probably died of natural causes in his sleep. On the following day they released a statement via their record label, Season of Mist.
Prior to his death Bråthen was working on a documentary about the Norwegian black metal scene, entitled A Black Metal Year in Norway. Originally slated to a 2012 release, his death prevented it from being finished and released.
