A brief history
There is concrete evidence that once, centuries ago, Deirailsa was one solid planet. There are ruins, seemingly ripped in two, on islands hundreds of miles apart. In some of these ruins, fantastic descriptions of lost technology has been found, most notably the Warforged and Shardminds. Both living constructions, the creatures were uncovered in the wreckage of what appeared to be a great temple on the Dwarven island of Kauzza. With this discovery and the ability to construct reliable modes of transportation again, airships, the dwarves were the first race to explore other islands.
Using their advance technology, the dwarves gained favor and established trade with the orcs of Dòngwù Guójiā, forming a pact known as the Naval Alliance. Thus established, this new naval superpower began a swath of diplomatic and forceful acquisition of territory, from Sylvia toMykonos.
