Beautiful techbase map for arcane dimensions by Calluna Vulgaris. The level of detail on display here is really impressive. I do a lot of wandering about after finishing the map at 50~ minutes in searching for the secrets. I wouldn't bother watching that part!
Important note: If you choose to play this (and I strongly recommend it) then you're probably going to need the most recent build of ironwail to get it running at an acceptable framerate. Grab one of the builds from here: https://github.com/andrei-drexler/ironwail/actions (requires github account)
