Tyn (tjɛn)

The realm of the unclaimed dead is a harsh mirror of the mortal realm. Deep beneath Isesda a jagged place of razor stone and a ceiling of roiling magma lies, housing both the essences of dead mortals not sent off to the realms of other deities or reincarnated into new lives in Isesda and the myriad daemons that erupt from the firey stone of the realm. 
Named for the goddess Tyn, one of the Children of Eledra, who rules over this realm. To an outside observer this place seems horrible, a realm of vicious creatures and suffering, but for most who dwell there it is a place of peace. The essences who dwell there drift between pockets of experience, living in peace and happiness. The daemons hold no interest in souls already come to Tyn and so act more as a deterrent against outside forces that may seek the souls than any threat. Moreover, mortal essences are no longer bound by mortal perception and so do not experience it as we might. To enter the realm while still living is unheard of, though that may simply be because any who achieved such a feat died most swiftly and horribly in the success. 
Tyn herself resides in a house of stone and volcanic glass where she exists in solitude. Within these walls no mortal perception can pierce, but it is known that she has rarely held audience with others of her kin there as few other Children are willing to be so utterly at the mercy of their sibling as they would be in the heart of her own realm. 
There are stories that claim Void itself sought entry through Tyn only to be driven away by the lady of the realm and the combined might of the daemonic horde and mortal existence. How such a feat could be achieved by a single one of the Children is unknown and so many consider this the hyperbole of beings cowering before their own mortality and attributing incredible strength to its embodiment by extension.

Geography

In a very literal sense, Tyn is the reverse of Isesda, hanging below the world out into the Void. This simplistic reality denies the metaphysical nature of the realm though. In truth, there is no depth to which a mortal could delve that would bring them into the underworld. Yet simultaneously the two sides of the creation are physically connected, seeming to imply an enedlessly morphic expanse of earth between the two. What is known is that the magma which forms the crust of Tyn and connects to the earth of Isesda is indescribably hot, matched only by the flames of Raiei himself. 
Within its borders, Tyn is impossible to navigate logically. Space seems to expand or contract and parallel lines with sporadically intersect or diverge. The daemons seem to have no issue traversing this realm where physical laws seem so very malleable. Mortal essences do not perceive Tyn in this way, and as such simply drift between perceptions and experiences which at once exist both within and without Tyn.

Ecosystem

There isn't an ecosystem in the mortal sense within Tyn as nothing there requires traditional means to sustain existence. Instead there are the endlessly spawning daemons erupting from the molten stone and solidifying back into stone as they age alongside the procession of mortal essences which pass into Tyn from Isesda and which are themselves passed to their respective afterlives or left unclaimed to drift Tyn. There is no sustenance, no natural life as we know it. If somehow a mortal were to bodily enter the realm it is thought the heat alone would incinerate the unfortunate being, but if they were somehow to survive the heat and the daemons while clinging to the stone of Tyn starvation and dehydration would be guaranteed.

Natural Resources

The stone of Tyn is said to be harder than steel and hold a razor edge for all eternity. This is likely mere legend though as no smith has ever obtained such material. Perhaps if one could bind a daemon to their will such a request could be made, but the risk certainly seems greater than any reward.
