The incredibly lost squirrel has started to seem more distant over time. Either that planet is drifting away, or the squirrel itself is; probably the latter, if it's chittering around with no entities to tyrannize and nobody to tyrannize it.
The squirrel is still using all the Locate Objects every day; and it has requested spells reminiscent of searching for something through land and air and water. But Asmodeus has been down this road before; it's time to retrieve that pet squirrel.
Have a Sending, a Plane Shift, and a Homeward Bound. Hopefully that message is clear enough.
