You proceed onward, sloping gently underground. Maenor finds that the light begins to grow dim as you progress further away from the entrance, while Kalis and Coda find themselves walking into darkness despite the cleric's lead. Thankfully, the narrow passage provides those without darkvision the ability to feel their way forward, and the sound of Maenor's armor is like a guiding beacon. Maribel follows the elf obediently, led by the reins and calmer with each increase in distance from the snakes.
The natural tunnel twists and turns like a river, cutting off any ambient light from the surface and plunging you in complete darkness. In some places it nearly feels as though you've been turned back, but with diligence the path takes you deeper underground. Now the path begins to break, with cracks in the floor and abrupt shifts in level.
OOC:
Maenor, make a Survival check (at disadvantage unless someone decides to light a torch) to guide your companions across this Difficult Terrain.
