This is a composition for tunnels and sewers, and the creepy monsters that lurk within.
@carrieallen and @chrisroberts (The Masters of Lore) created several tunnels in the Splinterland lore:
In Khymeria there's Baluthar's Depth (or Deep) which holds a series of caves/tunnels (natural).
In Lyveria (in Anumun) there are sewers/tunnels that run under the city where the Peacebringers find refuge when running information across the land.
And of course, Molten Mountain is a huge network of tunnels and caverns that act like a city.
