Scycae, translating into Scycaen as the "Imperial Lands," was an empire in northern Somnum known for turbulent winds and intense heat. Nearly half its dominion was dominated by the Jozh-Mirozhae, though southern Scycae was more arable, and significantly more populated than the north. Between vast riches found in the Cindersands and agriculture from its south, Scycae became prosperous, despite troubles with pirates coming from the Siren's Isles.
The Imperium was originally called the Scycaen Empire, which had advanced outward from its capital Scil-Qallis. Scycae was so named after Scyseti, the "Soulflare Sword," which had been found by explorers in the Cindersands. Though the Epochal Artifact was difficult to wield, it was powerful enough to win entire wars on its own, and Scil-Torrena used it to conquer territories all the way to the Sea of Clouds.
Despite these advantages, Scycae was declining prior to Common Unification. For decades, none of its warriors had been able to wield Scyseti; lacking it's singular threat, many Scycaen vassal states had begun to feud and vie for their own power. However, in response to the formation of the Common League, the empire was completely reshaped by a paladin named Riyissan Terrescel.
Able to wield the Soulflare Sword, Riyissan consolidated power in a promise to fight off Iodun the Unifier, who had threatened to take traditional Scycaen lands beyond the Wyrmhorn Reach. In the Battle Of Sylphglade, he lead a garrison that soundly defeated the Common army, and drove their armies south of Scil-Torrenae. In a statement of might, he made Scyseti's Cut, which marked a new Scycaen border; peace was thereafter held with Commona for generations.
Riyissan used his possession of Scyseti and his status as a war hero to become the first Imperator of a new "imperium", seeking to re-establish its grip on the north. He changed many of the old empire's laws, and functionally turned it into a single-house monarchy under Terrescel rule. For generations, Scycae was stable, but as generations of his heirs proved unable to wield the sword as he did, the Imperium's grip began to weaken once again.
Residents of the Imperium natively spoke Scycaen, though many spoke multiple Languages and learned the Common tongue, which shared a similar script. The language contained traces of Common, Ardhon Miniel Elven, and Skypeak Dwarven, though how much each language influenced the other was a matter of studied debate.
