The High Aldwin
They were 18th, minimum:LIches in 1ed were anywhere from 11th to 18th level wizards.
You might have been confused by the HD at 11+, which, despite being d8s, I assume was because magic-users in 1E were limited to 11d4 hit points, gaining only +1 per level after 11th.
Where is that? I don't recall that at all...it would lose a level if its original body could not be found and eaten...
