A Past Soon Forgotten
Dread Lieutenants of the Lich Lord
These servants of the Lich Lord are powerful officers of the undead army. They neither fully alive nor undead. Instead, they are willfully in the process of exchanging mortal parts of themselves, sometimes even physical apendages, for more necromantic power.
You know of the existenance of at least two of them. One resides in the Cloud Peaks. The other somewhere south of Purskul.
