Population Migration / Travel
In the past centuries, the increase in power of the Necromancer of Dol Guldur has been responsible for the slow but steady diminishing of the inhabitants of the vales of the Great River. In the year 2063, the Wizard Gandalf finally enters the fortress to investigate the matter (songs and legends of the Woodmen have him led through Mirkwood by the young son of a hunter). The shadow over Mirkwood weakens and many folks that were forced to leave return to their lands: the Woodmen multiply and prosper in the following years, establishing settlements both east and west of the Great River.
