The Shadow Play Theatre.

A natural ampetheatre with high walls surrounding the audience seats and a high plain wall with a stage in front of it, located about a week's travel from Amber in Shadow (a day via Hellride, or Instantaneous via Trump). It is a source of oracles in the form of playlets performed by silhouttes on the wall of the stage, cast by the sunlight streaking through a narrow slit in the back wall of the audience, or acted out on the stage itself by an anonymous cast. In the way of oracles, the scenes presented are very allegorical and metaphorical, not easily deciphered.

The theatre was visited several times over the course of Through A Mirror Darkly, most notably by Shizumaru for insight into VENIR 2.0, and by Corrine, Hiko?, Juri of Avalon, and company after escaping Gamber.
