From QuakeWorld Wiki
The Immortals (IM) is Polish QuakeWorld clan formed back in 1997 by Plast who invited five best Polish players of that time period: Headhunter, Macler, Tajrou, Sharky and K3. The clan was unbeatean (meaning never lost even a single map) until first Polish clan league final versus another Polish clan, Frag eXecutors (FX). Many players wanted to join The Immortals but the only one who eventually got in was Eternal. In 1998 Macler left The Immortals for his own clan, The Bad Boys (BAD), some other members went inactive and the rest of The Immortals joined with Brotherhood of the Herb under new name, Death Dealers.
