Notes on Mongoose's Deepnight Legacy 07 November 2026

I've been running Mongoose's Deepnight Legacy, first segment of the Deepnight Revelation campaign. And it needed some help.

The organisation is terrible, even by the standards of Mongoose. For a start, while there's a decent map of the base where most of the action happens, it has no scale and says nothing about the size of the resupply ships (which are, in practice, about the size of the base's footprint, since they're cargo haulers and the base is quite small); what's worse, there is no map of the wider area. Here's a non-spoilery version of that, which I had to make for myself! (SVG behind the link.)

Contour map

(Here is the generator I used for the terrain, based in fact on the valley where I live; then I had to try to work out just how far the observatory is from everything else, because no distance is given… the other location which I won't name for spoilery reasons is due north from the camp and a bit east, where the ground starts to rise.)

The ship deck plan is usable, and shows the lower deck as a divided cargo hold (the aft section can be used as a fuel tank) with an access passage running port to starboard between the parts, with a personnel airlock on each side. That makes sense and it's what I used. The illustration of the ship, however, clearly shows the airlocks on the upper level.

The other extra bit I did, which I can't fairly blame Mongoose for not including, was to get a friend to record an audio log (provided as a handout) and play that during the session. This was most effective. Thanks!

But organisation in general is quite poor. let's say the characters have gone to the observatory and I want to run the scene there. For this I might refer to:

  • NPC illustrations and personalities (pp. 9-10)
  • Text description of the observatory (no map) (pp. 17-18)
  • Stats for the NPCs (p. 32, with more personality notes)

and my inclination would have been to put them all in one place, or at the very least combine the two NPC sections into one and give some cross-references between places and people. (Mongoose is teaching me a lot about how to organise my own materials. Yes, I realise that this is designed for print as well as PDF, but you can put in page cross-references automatically…)

Who knows what about the story of Eleanor Braam? What do the survivors think about the carvings camp? Why don't we have names for all the dead people? Are they just scenery to make the players feel sad? Yes, of course they are, but they shouldn't feel like it. (Here's my list; I've used Vilaani names since we're at the far end of the Imperium fron Solomani space. Italicised names are canonical.)

There is a decent adventure here, but my goodness it takes work to prise it out of the book.
