Greater Yondarin

Greater Yondarin, in its day known as the Kingdom of Yondarin, was a large kingdom which emerged in the Iolìor region following the withdrawal of the Old Empire from the area. It was founded in 289 OA by King Ezherin I. Despite remaining on good terms with the neighbouring High Kingdom of Ocania, the two realms clashed in the Petty Wars of the third century NA, weakening both. Yondarin collapsed into civil war by the start of the 4th century NA, and it was soon after absorbed by the rising Hosaq Empire. 
After the collapse of the Empire, the lands of what was Greater Yondarin were split into two realms. The larger and more populous of the two is now known as the Kingdom of Yondarin, whilst the southern, smaller kingdom is known as Lesser Yondarin, despite its rulers styling themselves Kings of Yondarin as well. The rulers of Lesser Yondarin claim descent from the original dynasty of Ezherin I, thus refusing to submit to the Kingdom of Yondarin, whose kings were once blacksmiths.
