The characters are starting in the town of Brindol, located near the center of the Elsir Vale. Winterhaven lies to the east on the mountain range that separates the Elsir Vale from the Nentir Vale. Overlook is at the far western side of the vale.
If you’re making a character using the “D&D Character Builder”, you may use backgrounds related to the “Scales of War” (and “Chaos Scar” settings, if they add them), in addition to standard D&D backgrounds. We are not using “Forgotten Realms” or “Eberon” campaign backgrounds.
