Lesharea

Lesharea is the south-reaching arm of the great island of Taijuria, extending down into the warm waters of the Emerald Ocean, and is also known simply as South Taijuria. It is a prosperous and fruitful land: Gold and precious stones are mined in its central highlands, and valuable trade goods such as camphor, spices, aromatic resins, and teakwood come from its coastal regions or the wooded valleys running inland. Most of Lesharea is under Sarcian rule, forming one of the empire’s richest overseas provinces. The Sarcian city of Bhatrichor, a formidable fortress and major seaport, is the biggest in the region and the seat of the viceroy who governs Lesharea in the emperor’s name.
However, the southernmost part of Lesharea was invaded by that rare breed, seafaring orcs, in 1252 CV during the last stage of Gol Garga’s terrible conquests. They caused great havoc, occupied and plundered a large chunk of territory, and advanced far enough up the eastern coast to threaten Bhatrichor itself. Sarcian forces on Taijuria were scanty at the time, and the empire’s generals certainly did not expect the province to be attacked (by an orcish fleet or otherwise). Two legions of the emperor's best troops were rushed to Bhatrichor as quickly as possible, but they took months to arrive and the orcs had established themselves quite strongly in the meantime. 
In the three years since, the imperial legions have since managed to push the invaders back substantially, but the orcs have also received reinforcements via sea and remain in control of a sizable part of southern Lesharea. They have erected fortresses, built more ships, and still stubbornly resist the Sarcian campaigns against them. They have also (as orcs are wont to do) spread out and infested the landscape, infiltrating into Sarcian territory as raiders and bandits, establishing hidden camps in the hills or hiding out in caves where some of them will doubtless become permanent inhabitants. Even if their redoubt in the peninsula's south is crushed, the countryside of Lesharea (especially in the uplands) will probably be plagued with orcish marauders for years to come. Meanwhile, orcish pirates operating from havens along the shores they control have also made themselves a menace to shipping off the south Taijurian coasts, out into the Emerald Ocean, and east into the Shreenwater.
