Slumbering Sanctuary

"A mysterious energy runs through these walls, like blood through living veins."

The Slumbering Sanctuary in a fourth level biome. An old sanctuary with blue color theme and some enemies, at first it appears as a blueish coloured sanctuary with a peaceful, soothing atmosphere and statues of enemies in the background. You can find and activate the AT (Ancient Temple) Switch, which open all the yellow doors that leads to the outside portion of the level, and also changing sanctuary's color theme to orange. Most statues you encounter will be pure decorative until activating AT switch, which after that will glow yellow then come alive starting to fight you if you get close to them.

A Caster elite with the Spider's rune can be found here. He disappears after being defeated once.
