Abeyance is a demiplane created by the chronomancer Etyad the Timemaker to serve as his home and workshop. Etyad is the only resident of the highly unusual demiplane, though he will accept an audience with any who seek his expertise and can gain access to the plane.
Abeyance has the appearance of a massive yet intricate glass and bronze hourglass, hundreds of feet tall - besides the contents of the hourglass, there is nothing else in the demiplane. Between the two halves of the hourglass, at the midpoint, lies a glass sphere roughly forty feet across. This sphere serves as Etyad's living and working space, full of magical items in varying states of completion. Around the glass sphere sand flows between the two halves, visible to those inside.
The hourglass takes an entire day for all the sand to fall to the bottom, after which point it automatically flips and the process begins again. Time is fluid and malleable in Abeyance, and a day might have the length of a minute in the Material Plane or many weeks, following Etyad's whims.
