I am currently writing a short story that may become a novelette set on Irqulnirn after an apocalypse. It actually inspired the creation of quarzyls.
This is the historical background for the piece. Some of the details are incomplete at this time and require more worldbuilding.
Irqulnirn is dependent upon quarzyls’ life-giving and creating abilities, because of its distance from N’Zembe. This is common knowledge among Irqulnirn’s inhabitants, yet not often are its full implications considered.
The quarzyls live throughout Irqulnirn, nourishing the soil and assisting in the growth of plants and sometimes animals. However, a large concentration of them live in the country of Arziki, creating a greater level of prosperity there than anywhere else on the planet.
Jealousy sparked in the hearts of the other peoples, and they decided to band together and attack Arziki. The quarzyls from elsewhere gathered in Arziki with their fellow quarzyls. The quarzyls, despite preferring small groups, began building all around Arziki’s borders with magic-resistant stone mined from their country and nearby lands. They built a wall two hundred and fifty feet tall, five feet wide.
As soon as the wall was tall enough to block the quarzyl’s magic, Irqulnirn began to suffer. All the other species began to die from starvation and suffocation. The plants helped regulate Irqulnirn’s atmosphere and temperature. Now without them, there was no hope or possibility for life outside of Arziki.
The quarzyls had not thought through the results of their actions, not fully realizing how dependent Irqulnirn truly was on their magic. The other species did not realize this either.
Over time, after those first quarzyls had died and several generations passed, everyone forgot about life before the walls. Life with other species. Life elsewhere on Irqulnirn. The people were content, lacking nothing, creating all they could ever want or need. However, their true purpose had been lost. They had killed their planet and all those who depended on them. Those they were meant to protect and nourish were killed at the hands of those who made their lives possible on this far away planet.
One small green speck exists on Irqulnirn when viewed from space. Eventually, it too will cease, once Irqulnirn drifts too far from N’Zembe for even the quarzyls to live.
