Geingil Spigot rises up from the deeps along an active lava tube. This tube circles around an inner shaft which holds a staircase built by and for the fire giants. Lava barges can move up this lava tube, rising upward with the current until reaching the molten river Ofli Hrolmir. A descent down the lava river can be done by lava barges, wading or swimming for fire-resistant types or by taking the stairs down. In either case, the descent ends two miles down at the Great Vein of Surtur.
