Nate did a compatibility build with DoD but it was on his twitter feed and does not appear to be in their You Tube Channel.
There were a bunch of pictures of it in KS Update #18.
The more we think of the lava river, the banks and the volcano, there is nowhere you cant have a eruption and lava flow.
You just need a flat surface to put them on, DF have shown compatibility with other DF builds. But there is no reason you can add this to any setup, especially battle mats as they are deliciously flat
Definitely running a W40K Cities of Death game with added volcanos and lava flows, our desert and even our winter boards are going to be getting the lava treatment
Would be nice to have an end banks representing the leading edge of the flow, though a couple of convex curves would do the trick.
