Himmel.
As Himmel emerges in to this new space, creeping wide-eyed in to the alien glow of some strange looking growths near the entryway, he isn't sure how to feel. In truth he cannot feel. He is awash in an emptiness that is made more obvious to him as he peers around at the immensity of the space.
The glow is ugly. It is patchy, yellow for the most part, with shifting greens muddying the edges. He passes near the light and wonders where it is coming from - is this magic? Is this someone's spell? How could it last so long...?
Himmel then ducks among the lights. He is cautious upon entry in case the light is actually there to hurt him. A tentitave placement of one hoof, then another, then his nose sliding beneath the light; but as he slips in to it the light becomes hazy and seems to transition in to a sharp blue, like a robin's egg. The change makes him seize up and remain still for a few seconds, expecting something to happen.
Nothing does. It is just light. His body relaxes and he shakes his shoulders and neck, feeling tension there that lingers even after the rest of him calms. He reaches with his snout towards the light and noses at the gills of one of the odd growths, snorting as tiny beads of dust - or something similar - touches him.
