Liches/Mummies can age-die as well now. Normal age for a lich was said to be somewhere around 1000 hours or so. Add leader age to that... + the chars that were affected by this as it went in got their aging reset or something like that. (can't be bothered to search up the post about it.) But I THINK that we'll see a certain lich age-die soon enough. Provided she begins to login a bit more frequent and for longer hours.
