Era beginning/end
After the collapse of the Dwarven States, daoSvor, Aricc, Crahn, Laohor, and Rheddor, the human settlers of Gruthe rose to prominence in three immigrant populations. From Tcha in the West, were the *Gzīel peoples who would become the Qhélssénnish and Kharnnish; from Ptarro in the East, came the Ptarshishin; and from Xitzol in the South, came the Tlatotlys. A relatively easy peace was drafted between the three colonial powers given the vast spaces that separated them. The era named for this division of the continent was called the Three Kingdoms.
Still reeling from the devastation of centuries of conflict and plague, the surviving Dwarven Kingdoms withdrew into themselves leaving vast swaths of territory depopulated, but easily cultivated by subsequent settlers. The humans who arrived in this period, augmenting the resident humans, became the dominant powers on Gruthe. This structure has remained into the present; the Dwarven Kingdoms never regained their stature; the Goblin Kingdoms and their people expurgated from the world; and the Troll Kingdom withdrawn into the hidden regions of the Black Isles.
