Near the range where one can acquire their first sect cantrip, there is a general circle requirement to be able to use them, but how it pays off!

[Plane of Probability, Eternal Plain.]

A dull grey light illuminates the featureless terrain, forever presented by a drab, neverending sunset that is devoid of bright shades of color.  Where the sky and ground meet, haze swirls, obscuring that boundary, its definition apparently only from that pale sun.  Above, streaks of oddly-formed clouds run to the horizon, carried by potent and invisible winds, and all around a deadening silence muffles this place's every unidentifiable sound into a soft whisper.

Also here: Talian, some people from various sects, Taramaine, Tezirah, Karosti, and some fledgling scribes.

Obvious paths: none.

A runaway Heritage House member spreads her hands apart, then brings them slowly together with fingers interlocked.

A representative from the Celestial Compact turns her gaze heavenward and traces a series of lunar sigils in the air.

A lost Gypsy makes a careless gesture as he begins an almost musical chant.

Eyes unfocused, a Monk raises one hand before him in a studied gesture.

A drifting Nomad whispers softly as her words are carried away by an errant breeze.

With a sly smile, an innocent Tezirite murmurs a tenebrous phrase.

Prophets? Anyone?

Also, a big thanks to Lenarra, Tykyra, Rumet and Sydnee for letting me know.
