Time is on your Side

Everywhere in the dungeon the PCs go, they find little trails of slime, though they seem to only go directly down the middle of the hallway, in a straight line, until making turns at perfect right angles. A PC who makes a 4d6 roll under their Wisdom can hear a slight ticking sound, which seems to be coming from within the walls. Attempts to destroy the walls yield no information.

If they are still there at midnight, a series of chimes sound all around them. Tiny snails with clockwork shells slither out of holes all around the dungeon. They form a procession and move into the nearest room. Once there, they follow each other around in a circle for one minute, until a second chime sounds. They then return to the holes they slithered out from.

Digging in the Sand

Bones. So many bones. How many people have been buried here?

You find a rusty long sword and a small, golden vulture head worth 250 gp.

Red Sand

The sand here on the edge of the sacrificial ground is loose and looks recently churned.

Vulture Priest

The Vulture Priests are the enemy of knowledge and enlightenment. They seek to bring the eternal silence, the end of all things. Decay and obedience is their only god.

Immune to the Divine: The spells and powers of clerics and paladins have no effect on them.
Weapons: They frequently use wickedly curved daggers, which they use for sacrificial purposes.
Soul Clouders: There is a 10% chance that any Vulture Priest can use the sleep spell once per day. The targets are still awake, but they are beset by such a deep depression that it has the same effect as sleep. They may only watch what unfurls around them.
