Your Astronomical Survey vessel has found a wormhole to a new system. Circling one of the uninhabited planets is a mind-ship from a civilization that departed for higher space more than 3,000 years ago. 

Your task is to see if the mind can be brought back to a conscious state, and if not, to salvage what you can.

Inspired by the Bitsy Ghost Ship Jam, although not completed in time to enter it; and also by (among many others) Aliette de Bodard, J.R.R. Tolkien, Iain M. Banks, Lois McMaster Bujold, A.A. Attanasio, and Karl Schroeder.
