Poor lost little shadeling...
The orange, sandy dunes of this tangible realm were strange. He'd seen the Eversands before, witnessed their ever rolling majesty in the realm beyond life, but they flowed with a certain... difference. They seemed to hold more weight here, fascinating in truth if not for the fact that they served as something of a prison. He didn't fully understand what had brought him to this place, only that he'd been following a much older Shadow's tracks.
Masque one minute, here the next. He felt weak and impressionable, fleeting. Rin did not hold a form, could not force himself to hold a form even, and the latter was frankly horrifying.
Imagine his surprise when he found a nice meatsuit to wear, through which he could interact with it all. Some wandering archaeologist who had been studying local ruins. It was far from an ideal sleeve, of course, certainly nothing at all alike how he would typically hold himself, but the discovery of such an interaction had granted him the ability to practice possession if nothing else.
Frankly over the past few days he'd gotten particularly good at it! That was until the body keeled over one morning, and refused to move. Glassy eyes had stared at his shadowy form unblinking, until Rin lost interest and drifted away. He much preferred his natural state anyway, there were plenty of creatures in this realm who sought to gnaw on the fleshy man, but they couldn't much get a grip on him now could they?
Mhm, that was perfect for him. To allow him time to figure it all out. And there was so much to see, so much to observe. Small creatures which skittered through the sand, large behemoths which prowled before tomb entrances, runes and artworks etched into stone. His excitable self zipped this way and that, soaking in as much as he could to bring back with him to the Nether. If indeed he'd ever make his way back there.
Ever the optimist, Rin was hopeful he would.
... Somehow.
