Aroden’s great working, that weaves the ley-lines that cross Xopatl into a living web that will keep their crops alive even in the absence of a sun, is almost complete. Unfortunately, for complicated geomantic reasons, one of the kumaru trees that anchors the working had to be placed in a high valley of the Mildanesi Mountains, uncomfortably close to a small but persistent rift to the Plane of Shadow. It’s this tree that is, somewhat predictably, having issues.
The valley is impossible to Teleport in or out of due to the aforementioned planar rift, so she and Aroden set off on foot from the nearest safe Teleport location. Somewhere along the way they’re set upon by a pack of shadows, and something commanding them that can cast a Deeper Darkness that even Aroden can’t dispel.
When the darkness clears, she’s not where she remembers being, and Aroden is gone.
