Endearing Shackles is a prison world for primordials and their minions captured in the Creation War (1486 DE - 8777 DE).
When Thasmudyan became a god, he was sent to this world. He raided the world’s countless prisons, knowing that on this world you never age, so they had to be stocked with potential minions. Using necromantic magic created by Maen Saetild, he created an army of undead giants. A few of these he left with intellect intact, knowing that he couldn’t command them all. These intelligent ones, became his undead war masters.
