A Gothenburg Thrash-Death Metal act convened under an original banner of REDEMPTION during mid 2001 by ex-ZEPTIMA personnel singer Henrik Blomqvist and guitarist Oscar Albinsson. Subsequent recruits included bassist Thomas Broniewicz, drummer Dr. Rhythm and former ZEPTIMA bassist Christoffer Noren took charge of rhythm guitar. The band switched title over to SHADOWBUILDER, inspired by a German language film of the same name, and brought in Pontus Jordan of DR. ICE as their new drummer. However, Jordan soon bailed out and Broniewicz, as 'Varulv', became lead singer for Black Metal band FIMBULTYR. Uful Demir took command of the drums for the opening March 2002 demo 'When God Created Light'.

Upon Noren's departure in mid 2002 Erik Johansson enrolled as new second guitarist. SHADOWBUILDER cut a further demo session in 2003 entitled 'Bone Ritual'.

Singer Henrik Blomqvist is also active with DISFUCKED, alongside band mate Oscar Albinsson, and COLT.45. Bass player Thomas 'Varulv' Broniewicz, guitarist Erik Johansson and drummer Ufuk Demir industriously pursue outside projects such MURKELHEIM and FIMBULTYR. The bassist also participates in T.A.N.K. and NECROTECH VAMPIRES. Demir cites membership of COLT. 45 and the DEATHMANGLERS too. In February of 2006 the drummer joined HEED, the group assembled by erstwhile LOST HORIZON members singer Daniel Heiman and guitarist Fredrik Olsson.

SHADOWBUILDER folded in 2007, with erstwhile members Uful Demir, Henrik Blomqvist and Oscar Albinsson formulating BECOME IGNITION.
