Aclys formed in October 1996. After recording the first 4-Track sametitled 7", released on the legendary Per Koro Label, aclys achieved a well-know name in the german HC-scene. With their first full lenght album "Helduntergang" in 1998 a german HC-Milesone was set. Followed by their "Liedergeburt" album in 2000 aclys' music became know europe-wide and was well apreciated as highly innovative and technical New School Hard Core, which later should be known as MetalCore. Allthough the band took a four-year time out the band never split up.
