Petrosa

Petrosa is a continent on the northeastern half of Ecorem. Together with Irgaedera, it makes up the Ecorem landmass. Its entire extent covers tropical and subtropical rainforest, tropical islandic, coastal, temperate forest, mountainous and tundra climates. A quarter of its land area is made up of more than ten thousand islands off its eastern coast.

Age of Movement and Expansionist Age
During the Expansionist Age, Petrosa was occupied by countless tribes, among which the largest were Beghula, Orsand and Sola, which have extensively shaped the development of society across the continent. Orsand and Sola also had a major seafaring presence, while the Latis tribe claimed exclusively islandic territories in the Las Hocorexadier (Uncrossable Ocean) and the Las Marr (White Ocean).

Hebis Loricoda
Following the Red Ring Pact, most tribes settled in fixed territories across Petrosa, although most of these tribal territories saw their borders change dramatically over the course of their history. The Solan Territory broke up into Aora and Sonora Ere in 1250 BOG following Onao's secession in 1512 BOG, while Bel (Beghula's territory) saw edge territories break away into present-day Cerdolia and Elraka.

Age of Open Gates
Following the Opening of Gates, the principality of Latis dissolved into Coroca and Eregoda Niel in AOG 25 under the claim of different deities. The two archipelagos were geographically separated by too great a distance to be ruled centrally. Likewise, Oro separated from Sonora Ere under the defence of its deity, Omari, and Sonora Ere--then made up of Cado Saloda and Cado Ihira--later became Sonora and Astra respectively after Astra seceded.

Smaller tribal territories, such as Beorna and Enmira, continued to thrive across Petrosa, and have proven more stable than their larger counterparts.
