Well I included 13 Silmarillion events, but most are actually Second Age events that map perfectly fine. Three of them are First age so it's a bit fudgy.
The project has no Beleriand events... they literally cannot be placed because Beleriand sank beneath the sea after the War of Wrath.
CuiviƩnen it tricky. The Sea of Helcar where it sat was reshaped when Morgoth's strongholds were taken out, so that is approximate.
Would love to make age-appropriate (ha ha) maps, but I only had this one to work from.
