I'm not sure permadeath is the right word for it. A group of players on Khyber, mostly from The Core, are forming a new open guild for epic level characters. The focus will be on exploring the new world and experiencing fully (dungeon crawling) the new quests.
Basic ruleset will be simple: any 20th level character can join; group with guild only, flawless victory for every quest; and maybe a limit to total number of raises based on base constitution.
Send me a tell if interested.
