One of the many God-Kings of ancient Bulwar who presided over the kingdom of Barzišah. While the God-Kings are known for their genie-binding, Irsakar's most well-known accomplished was as an accident. In 2120BA, he ordered a survey of his realm which included the modern-day Tungr Mountains. It was during this survey in 2119BA that the abandoned hold of Ovdal Tungr was rediscovered hidden among the mountains. Upon its rediscovery, Irsakar gifted the hold to the dwarven population of his realm to resettle in exchange for their service. With Ovdal Tungr restored, Barzišah came to dominate trade in the ancient Divenhal Sea.
Despite the Kingdom's small size, its former geographical extent was made all the smaller following the Day of Ashen Skies due to the rising water level across the Divenhal. In fact, even the capital of the once great kingdom has been claimed by the sea, having been located at the former mouth of the Irasqqu river, now several miles off the coast. As the discoverers of Ovdal Tungr, the kingdom had fallen into mythical status until the late 1700s when divers on an expedition from Ovdal Tungr found the ruins of the great city, following an ancient map discovered in the hold's archives. In this way, both Ovdal Tungr and Barzišah found each other.
