The main Demon from DEMONSBANE, he was enchanted by the Glyph of Invincibility - "He cannot be slain by any hands alive, be they mortal or angelic"
So was he ever killed/beaten/slain? Bottom line, by lore, does he still "exist"??
I just read that he was eventually slain by siggard. But siggard was living wasnt he? How was he slain? and the year ws 308 or so... Arent we close to 1308 or so in diablo lore, so in theory diablo soon may be able to again cast the glyph of invincibility, of which he can only do once a millennium (1000 yrs)
I find it a slap in the face to those who wrote the books for.Diablo to then be told that their work isn't to be considered to be even true. Even if they don't really match up all the way they still had her good stories and were great for when they were lore. But now they are just bleh. But anyway to answer the question... siggard was killed in battle but he's soul was basically restless and he couldn't die till he finished his purpose in life and death. And that was the only way to kill the demon by the hand of the unread.
