Dark coloured walls engraved with Ul'kari glyphs. Three glass lens doors; north, south east and south west. In the centre a set of large mirrors split a beam of bright pulsing light coming from the north to the lens doors in the south. Every five rounds, the light pulses brightly enough to blind on a failed Save v. Spell. The doors open and close quickly.

• Glyphs — The secrets of light bundling according to Ul'kari wizards. A magic-user who studies these for 72 hours will learn the Light and Darkness spells. Studying for a month can teach the invisibility spell.
