Trimfect (or Toni), the author of this mission, has shared parts of the story. I'm reading from TTLG forums. This is the mission that gave LGS consideration to release DromEd and give us 25 years of FMs. It took him roughly 2 months to create this, because back then even TLG people didn't know how to do everything. The mission's archive date outdates some earlier missions because he re-released with some bugfixes. But this was the very first thief mission outside the campaign.

I rate this average as I would if I didn't know the story. I don't give it much replay value. But I do it with respect to one of the factors we still enjoy new FMs today.
