Modular Illuminated Tunnel Pieces

Slab

SpiderlessGwen created the original version of this, and it’s great.  I made some tweaks to it: tightening up the floors, sealing any gaps between tiles, adding a bit more interior illumination via the magical blue crystals, and tweaking the ceiling spacing. I also added some swamp tiles to the cavern floor tiles to give it a distinguishing texture as I found it a little difficult to navigate curves/turns on the original.  The four original sections remain: a two-way split, an elevation segment, a 90-degree curve, and the flat straightaway. Thanks Gwen for this fantastic slab.  Anyone who uses this in a public map/board/slab, please credit Gwen as well as me.
