The Battle of the Caeled Coast occured during the first part of the Crystal War before the Fateless One was slain in combat the first time. It was a series conflicts between the Alfar Army and the Tuatha-Deohn. It happened after the surprise attack that the Tuatha did on the Plains of Erathell that the fae consider the Night of Blood of Fire, and after the Fae acheived their first major victory on the Battle for Galafor Plain. The Tuatha were pushed back in a series of conflics where the Tuatha regrouped in Klurikon. These conflicts made up the Battle of the Caeled Coast.
Note: I should have a good, more in-depth story over these conflicts either by the end of this week or by the end of next week. I should also have a page about the Night of Blood and Fire.
