Another sector and a bunch of detailing accessories are also in the post, prototype corridor section is in the pipes. Test run with magnet coupling suggests they aren't going to be necessary but obviously will be for swappable wall sections. Kind of disappointed with the quality of the Honoured Imperium set - doesn't appear to be miscast, just a bad mold with pretty sparse sprues - but OTOH I didn't realise the shrine set comes with a different (better) set of floor tiles which is super handy since I probably need to buy at least another four of them.
(Hmmm, maybe this is getting out of control...)
Edit: Oh yeah, GO 'NUCKS GO!
