Yes I am aware that locations can be 'anywhere'. But if you GM like I do, you probably want to have major locations mapped out ahead of time (or at least have known options that make sense).
Starting this thread to map locations somewhat logically, based on provided information:
This first entry is based on history presented in the GM guide:.
500: Ailanders enter Ravenland told to stay south of the Seyster and Elya. This is important for the location Glethra (see Year 690)
610: Gold discovered in the river Wash, which feeds into Lake Claye U27 (Lake Claye on the map is called Clay's Eye in the History)
612: Falender marked on the map at location Ad23
690: Gold found in Glethra Mines in the Thynde Range. The Thynde Range runs up the entire Western side (at least, that makes sense to me). Dwarves from Stonegarden fight the humans who mine the Glethra mines because they are in lands that are forbidden to humans (north of the Seyster). So Glethra makes sense to be the mine at D12, which makes E8 or K5 logical locations for Stonegarden.
800: Teramalda founds Alderstone I40
820: Teramalda marches on Lumra with its blood red streams (Lumra is called the Stoneloom mines in Ravens Purge beta - said to be in a mountainside). In 852 Martea flees towards Wailer's Hold but has to divert to Lumra so it needs to be near Wailer's Hold. The castle at P26 could be Lumra and that makes the mine at O28 in the Arina Forest look like a good choice for the Lumra mines or Stoneloom mines.
869- 874: Zygofer's troops conquer and destroy the elven city of Varassa (N19) said to be in the Arina Forest but the map has it in Feulenmark.
877: Therania tires of king Algarod's reanimated corpse and sends him to command the fortress at Weatherstone. Assuming the undead don't travel far, Weatherstone should be in the west. The fortress by Blaudwater looks good but since Zygofer only sensed Merigall in Blaudwater when he moved into Alderstone - it seems unlikely. The castles at I31 or at P47 seem like the best options.
880: Zertorme has withdrawn to a place by the ocean. Zertorme is in Amber's Peak (Raven Purge beta) - a ruined fortress on the plain. "The Plain" is Margelda plain. Location Ab20 appears to be the only map location that fits.
