The calendar on Euclid is split into six months, each named after a Power and with sixty days. Due to this, a year lasts 360 days.
- Centenus (Centaur)
- Socielus (Sociones)
- Ibialus (Iblis)
- Vritras (Vritra)
- Xerus (Xeren)
- Plutonis (Plutarch)
The Euclidean calendar is typically split into two dating eras:
- Ante Tumultus or AT: A period of six-thousand years, starting in Year 1 with the creation of the world by Xeren.
- Tumultus Post or TP: The current period, which began when Gabriel Alchemilia opened a portal to Eden and angels came through. This resulted in a global war as humanity began to fight for their existence against angels and demons.
The regions of Euclid consist of the five continents and the cities across them.
It is led by Ki'Yoki, a cambion.
Muné is the most war-torn continent, a large portion of it being under demon control. It has a population of twenty million humans, sparsely gathered in the few remaining towns. Located near the northern tip of the continent is the Smithson-Reed Ferry, periodically transporting people to Aiola as part of a humanitarian effort.
Much of Muné is dense rainforest. The continent is known for its erratic climate and exotic features originating from Eden. Weather patterns shift wildly, with blizzards often happening in the warmer months. Packs of birfi, a large species of bear from Eden, are commonly seen.
Traveling through the continent is extremely dangerous. Headre is a large town of skinwalker demons that pretend to be humans, luring in those that pass by and kill them. The large Blackwell Forest is home to the infamous Beast of the Shadowlands. Thousands attempt the journey to the Smithson-Reed Ferry each year in search of safer lives.
ThalesSilivia, the most populated city on Euclid. The northwestern part of the continent is a desert, home to the native sand crocodiles.
Thales is the birthplace of many of the characters in The Demon's Light, and the setting of all Season One episodes. During an ancient war, Thales was transformed into a land of greenery from a desert by Xeren due to the citizens of Thales defeating an invading force of atheistic barbarians from Nuyö.
Euclid uses a globalized currency, functional around the world, known as gil. Gil comes in denominations of one gil, ten gil, fifty gil, and one hundred gil. Further transactions can be done through paper bills attained in banks worth one thousand dollars or more.
Gil comes in thick round coins with heavily serrated edges. Amounts of gil are written with the symbol 'G'. (ex. G200.00)
Weather and Climate
The weather on this planet varies depending on what continent/region one is in. Nuyö is the coldest continent, whereas Hala is the hottest.
Climate does not function like most planets. It is determined by an invisible line going down Euclid. The top of the line is the coldest and the bottom is the hottest, with a gradient in between.
Humans were the dominant species on Euclid prior to the Great War, where angels and demons from Eden invaded. The human population has been substantially reduced in most of the world, with certain exceptions. Hybrid species are uncommon, but not unheard of.
Other native animals include catulus, chicaro, and leviathans. Native plants include Gladean Oaks and Halan Firs.
Due to the culture of Euclid, religion is a sparse thing, often held by "fanatics" and those disenfranchised with the order of the universe. Most religions are practiced in small organized groups:
- Communion of the One God: A devoted following of Xeren from early-AT Nuyö, their group would eventually die out with the rise of atheism in the region. After Xeren was slayed by the Powers and his soul released itself upon the world, the group was used to manipulate the people of Nuyö by the Nuyö-Dyavol Coalition.
- Nirvanists: A group loyal to the Powers, wrote tales and fables about each of them that became famous for their large catalog of knowledge
- Lordists: A relatively unknown group that eventually merged with Nirvanism. Group members simply worshiped each Power for who they were, without any one moral code holding them all together.
