The deck plans section of Accretion Disk is excellent.
A laser crew's vessel is very central to any series, and the little idiosyncrasies and battle-stations really highlights the differences of each class. It all goes a long way to fleshing out the PCs' home.
The PDF download includes a deck plans document that features a Mandible-class vessel, but there's no write-up for it in the actual text. This is not an oversight, per-say, as the relevant section in the books mentions that it only covers six vessels... but color me disappointed by its absence.
The kch-thk design is suitably alien from the other ships, that I would have really appreciated a full description. :-(
I suppose what I want to know is; was this section written and then cut? Was it never written? Any chance of seeing it in the future?
