Sleepsor is a Dwarven miner originally from the Thair Mountains who occasionally goes adventuring to raise money for his next stake.
Sleepsor and his six brothers, Hapsor, Bashsor, Docsor, Grumpsor, Sneezsor and Dopesor, were working a mine in the forest south of Semmarch several years ago when they inadvertently stumbled upon an entrance to an ancient ruined Dwarven city. Unfortunately, all the brothers except Sleepsor and Hapsor were killed by various monsters they encountered. Sleepsor abandoned the operation and took up adventuring for a while again. He is now working a mine beneath Hermit's Hill just outside the town of Gaithos.
