Lost in the Dungeons of Madness
Rainald the Vigilant
Rainald worshipped the God of protection. He was the first of his party to die enough that he started hearing the hounds. He eventually ran off mid fight and felt enough shame that once he found a pair of double doors that he believe the exit he guards them sociopathic ally to help his party who went through. The party died shortly after entering but he still guards them, even from the reanimations of his old party, whom he has now attacked several times.
If the PCs find him, he will not allow them through the door without a fight. He is on his last life. Dying again sends him to the Mad God
