Realm of Solace takes place in an earth-like planet by the same name, with a single moon, orbiting a white star. It is a typical high fantasy world, with medieval and futuristic arcane technology elements, and some modern-day culture inspiration. Although Solace hosts 42 countries and 5 continents, the community focuses primarily on the Kingdom of Loria.
RoS depicts a world where magic is a widespread phenomenon highly relevant in the inhabitants' daily lives. Arcane power can be harnessed by individuals with the physical and spiritual capability to do so, becoming a skill honed through practice and study. However, it is also employed in technology powered by gems capable of holding and conducting the endless possible effects magic can harness. These translucent crystals are simply known as such, and come in a variety of sizes and shapes as they can be mined from multiple places throughout the world. They're made of a compound called 'cryptite', a naturally-formed material that conducts the planet's magical energies.
The application of cryptite and magic paved the way for an industrialized era that quickly led to the creation of production machines, automotive vehicles, electricity, household appliances, portable devices, guns, holographic displays, and even wide area networks with amplification hotspots for international communication. Polymers aren't widely used, as materials science isn't as developed as the use of magic. All this technology is yet in the process of improvement and further discovery, resulting in an inconsistent expansion all over the world. First-world populations and important congregations partake of these benefits more often than more marginalized areas, and some countries are almost strangers to the concept of magic-powered technology. In the Kingdom of Loria, certain settlements yet stick to traditional ways of living, with artisanal production methods and obsolete technology such as carriages, plate armor, and swords. This is due to the fact the rapid technological advance has yet to be fully assimilated by the slower-moving cultural adaptation, though certain settlements and areas such as Zerule, Wyle, and Adamantia, have been notoriously affected by the revolutionary phenomenon. People living in said advanced settlements, wealthier families, and governmental figures, all have incorporated arcane technology in their lives, making it relevant in today's life and trades.
Aesthetically, the setting retains certain medieval hints, with suitable fashion and architectural senses mixed with hints of our modern world. There are castles with electricity, skyscrapers of quarried stone, roads of concrete or cobblestone, automobiles and horse-drawn carriages, knights in plate armor or soldiers in powered suits, and even the equivalent of cellphones simply called 'cellstones', consisting of a handheld cryptite slate housing smaller crystals that operate the expected functions and display them on a touchscreen. All of these elements are subtly shrouded in a medieval Europe-esque aesthetic, and there can even be out-of-place constituents thanks to off-world interaction. Travel from other planets through magical or technological means is known, though uncommon or extremely expensive, but the concept of beings and people from other worlds isn't entirely beyond the populace of Solace.
Humans are the most common race in Solace, though they do co-exist with other sentient beings such as caspyrs, anthropomorphs, and certain kryssids. The Kingdom of Loria is particularly diverse, though humans yet compose the majority. Much like the aesthetic, society has ideals defined as a mix between modern and medieval - kingdoms, knights, nobles, superstition, public executions, and the occasional bout of backwards mentality, are all present in the populace's culture, alongside the presence of science, public education, magick studies, emergency services, and widespread human rights. Democracy is present in most governments, including the Kingdom of Loria, though the ruling house itself is not chosen by the populace.
All in all, Realm of Solace has a hybrid setting with significant freedom. Most concepts and characters can be easily adapted or incorporated to the world, allowing roleplayers to write whatever story they wish.
