Not super thrilled with how this painted up, but it is done.
The Dark Root itself is a 3D Print from a FREE STL that seems to have been removed from Thingiverse. You can still find it on-line (for free here) and if you have a problem getting it, it is free for me to re-post because it was distributed as advertising for a KickStarter and released under a creative commons - non-commercial license.
The second photo shows how I channeled DM Scotty to quickly make the Dark Root Vines out of wire, hot glue, and the clipped ends of tooth picks.
I've been using owlbear.rodeo - there are youtube videos and other sites that tell you how to use it, but it's a free simple table top. We tend to play with a grid.
