43D TOMB. Each of the doors to this room are marked with the following glyph of warding.
The power of each glyph is intense light. It will deal 28 points of burning damage to undead. Unlike other glyphs, it is visible and it will only activate for undead.
The coffin in the corner contains black dirt and the desiccated corpse of a bat-headed humanoid with a wooden stake driven through its heart. It is a vampiric being and will immediately return to power if the stake is removed.
Nykterran (Ancestral Dementing) Vampire (AC 1; MV 12”/18”; HD 8+3; hp 44; #AT 1; D 5-10 or by weapon +4 due to strength of 18/76; SA Energy drain, charm; SD +1 or better weapon to hit, limited spell immunity; XP 4328)
Though it has a head resembling that of a bat, it has standard vampire powers. The vampire is a member of the ancient race that was the progenitors of the dementings. Undead, it remained for millennia watching as its race sunk into atavism and decay. It speaks only ancient Nykterran.
