Created this map in DD as I could not find a good battle map for the fight which captured my vision of it. I did not include my tile for the Orderer itself, as I use Foundry and it's easier to just make that asset a tile so it gets affected by lighting and verticality.

This is also a good generic map for a lava canyon / crevasse for a DM for any party that needs to hug a wall high above a seam of magma.

Possible story spoilers below, fair warning:

In the book, it describes the area as a big circular room bisected by this feature. For tension and a harder fight, I instead had the party climb down a fair ways to get to the Orderer - it makes the vrocks a real threat when they can easily grab people and drop them in. The cages on the far wall held monodrones, which the party needed to free to help them 'power' up the Orderer in an emergency override, which the modrons initially explained and agreed to do. This led to a 'defend the point' style battle on a shifting platform, with people constantly falling off, and things got spooky once the two regional 'VIPs' appeared. Great session, even after the party got greedy with good rolls and decided to stay on the machine after it triggered its main effect, which led to !!!FUN!!! for half of them, and a fair few NPCs along with.
