Brothers of Death*, lol. Edgy as fuck but we were like 14 at the time. It was originally founded by hersztpl and was a Polish clan, then shadowelf was a leader for a while, then I got it and once it started dying, I got verax and shin-ryuu to join me and remake it into something international - Corrupted Waffles.
*Herszt couldn't into english at all, so the original name was even worse, Back of Death (what he wanted it to be called was actually Return of Death, kek) but we quickly changed that, like day two of clan's existence.
