Arddorwan Isyet

Arddorwan Isyet is a small planet within the same planetary system as Zeirenjier. It can occasionally be seen on clear nights without a telescope.

The surface of Arddorwan Isyet is completely covered in a dense, nearly solid gelatinous material that is dark blue in color, with large sharp rocks breaking the otherwise smooth surface. The entirety of the planet is constantly enduring hail-producing, windy thunderstorms; allowing little light from Arwae to make contact with the surface. The environmental hostility and the atmospheric makeup makes the planet's surface unsuitable for living creatures.

While we know what Arddorwan Isyet's surface is like, we currently have no way of exploring what is beneath it due to the thunderstorms destroying spacecraft that lands on it. Multiple accounts say that Harun-dor and Caulhrot are located underneath, as it is the only other planet in the system aside from Zeirenjier with a solid surface.

Harun-dor

Harun-dor is believed to be a region of pitch-black darkness and thick woods with the occasional lake, and nothing else. It is much larger than Caulhrot, and completely surrounds it. Harun-dor is also the only region of Arddorwan Isyet to contain hostile creatures, which are known as iykregul.

Iykregul are levitating, monstrous creatures black in color, created and led by the Lord of Iykregul, Luchirimyr. They are spread out across the entirety of Harun-dor and prey on lost spirits, effectively erasing them from existence when consumed. The growing population of iykregul in Harun-dor concerned both Jayir Hisadin and Lojue Hisadin, leading to the manual creation of many safe areas across the dark forest, surrounded in bright lighting. These places become safe for spirits by preventing iykregul from lurking in the area nearby, as they are repulsed by light. If left unmaintained for too long, however, the iykregul will eventually snuff out the light and make the area unsafe once again.

Lojue Hisadin, the Reaper, will patrol Harun-dor and eliminate iykregul to escort lost spirits to safety. He will also occasionally appear on Zeirenjier to collect the spirits of the recently deceased. However, as there is only one of him, he cannot personally escort each and every soul, thus spirits will most often be sent to a safe spot in Harun-dor and be directed to follow lit paths leading directly to Caulhrot.

Caulhrot

Once having survived the threat of iykregul in Harun-dor, spirits will arrive in Caulhrot. It is said to be a region for the dead and the living, one of perfect temperature and humidity that allows plant and animal life to thrive—the complete opposite of Arddorwan Isyet's surface. Many rivers and streams run throughout Caulhrot's land, feeding into the large body of water that surrounds the towering castle of Jayir Hisadin, the Shepherd.

Like Lojue Hisadin, Jayir Hisadin watches over the spirits that temporarily reside in Caulhrot, and takes care of them until they are sent back to Zeirenjier to live another life. The Shepherd will also enter Harun-dor and relight the paths that the iykregul have darkened.
