WorldWorkGames have released the Lair of the Dragon God: TerrainlinX Edition paper terrain set.
From their website:
The furnace heat of the lava channels flows throught the mountain…a mountain that was not originally the dragon’s realm. But today, he is the undisputed master. Welcome to the Lair of the Dragon God (TerrainlinX Edition), the latest in a series of conversion projects to take our previous sets and bring them up to the new standard, adding new life and new capabilities along the way.
