Darkness surrounded Fafnir on all sides, only the faint flickering of his own glow stones to light up the dungeon. They were woven into his mane and tail as well as in a large necklace around his neck and glowed with a faint blue light.
This area of the caves was open, lacking in any light of its own and as such completely empty but for his own shadowed form. Because of that it was as safe as the dungeons could get without any heavy protection from outside forces. Here he could stay deep in the shadows while still keeping track of anything passing by through just sound alone.
His hooves hit a stray rock that bouched away into the darkness before hitting something with a faint clink. Most likely another stone then. Best still to keep a careful ear out for any other sounds that might point to it being something less friendly than a lifeless rock.
Fanir carefully swept his gaze around what small parts of the area he could see, where the shadows flickered and the light just barely pierced through. Nothing moved and neither had the dust and debris been disturbed.
He let out a deep sigh of relief, no one had found their way through while he had been gone. His home was still safe.
With a lighter mood he picked up his step and moved faster towards the large rock formation he knew was in front of him and soon it towered up above him into the shadows above.
Fafnir did a quick glance over the rocks in front of him to make sure nothing looked out of place or any new cracks in the stone had appeared.
Nothing caught his eye and with careful and deliberate steps he jumped up onto the rocks, one two three and then he stopped. He was quite a bit above eye level for any of the common creatures in this part of the cave and there, set into the rock at an angle that was not visible from the ground or even directly above was a large branch like contraption, a brush of sorts.
Carefully he leaned down and took a steady grip around it with his teeth and dragged it out. He was even more careful on his way down, both to not risk dropping his tool and have it make a distinct mark in the ground and to make sure he did not risk injury by slipping. He was forever grateful for how dry this part of the caves were as it made it safe to traverse the outcropping in this way. Otherwise he would not have been able to hide his brush in this way.
Now with it in his possession he walked with it carefully slung half over his back to make sure it did not disturbed the wall worn path he was now once again walking on.
He walked for another minute or so before a small collection of nearly crushed rocks came up on his left. The sign of where to start walking into the darkness, away from the path.
Another quick sweep of the area and another all clear before he took the first steps of the path and lowered the brush to the ground so it brushed the dirt below him. It dragged along behind him and made the dust swirl around his hooves. A few steps later it settled, no signs of anything having treaded off the path to be seen. 

A faint light flickered in the darkness, making the shadows move as if alive. Their path against the beautifully woven cloth broken up by the glint of the metal thread set into the forest scene of the tapestry, glimmering like eyes in the darkness.
Fanir was home. He let out a deep sigh and moved towards the cloth door to his very own little cave. Just outside it he set down his brush in a carefully dug hole and dragged the ragged cloth laying beside it over it. This way he had a better chance of it still being there when he needed it again. The bats that roosted high up the cave walls above were curious creatures and had more than once tried to move it around.
The tapestry dragged heavy but oh so comforting against his back as he passed through the opening behind it into the small cave he had made his own. Directly behind the cloth the cave wall appeared only a step or two into the cave but with knowing steps he made a sharp turn left, a few steps forward and then right and moved into the cave proper. Here glow stones covered the far wall, set into the stone in such a way that their glow was hidden from the entrance. The lone glow stone at the entrance had its secret kept safe by the tapestry but if someone came close enough to peek in behind it, they would only find darkness and rocks in front of them.
With a deep sigh Fanir stepped into the cavern and moved towards the small stone ledge set into the very back of it. There he dropped his gear, the bags across his back and the filled water skins. The glowstone necklace he left alone, it was safer to always have it on in case of an attack. Beside the ledge a hole was dug into the ground and filled with dry mosses and grasses from the more humid areas of the cave and covered by pelts and clothes .
Now freed from his burdens he sunk down onto the padded sleeping spot and closed his eyes. His day had been normal, but still he was glad to be home.
He would give himself just a moment to rest his eyes before dealing with the day's loot. Just a moment.
