Lore says that it was burned to the ground as part of Zygofer's purge in 869 and is a place Aspis wants to see rebuilt so he can install a temple to the serpent god Wyrm there. All well and good. Per GMG p. 22:
"Settlers made their way east to the plains of Moldena and Margelda, which are suitable for horses and livestock. There they founded the wooden city Falender, which now lies burnt in ruins."
Then we read in the Bestiary that Nightwargs are a possible creation of a mad hermit, "The Dreamer in Falender" who tried to create a countervailing force to deal with the demons pouring into the land ~300 years ago. Lines up, it's 1165 AS as we begin.
Now the rub: In The Vale of the Dead adventure site, we learn of Kalmax of Falender, a "once proud and renowned rider in his clan" who is seeking to restore his name after gambling away his family fortune. Wait, what?
Is Falender ruins or was it rebuilt when the historians weren't looking? The reason I ask is I have a Half-Elven rider in a party that we're creating a backstory for via the Legends & Adventurers quickstart tables which has them hailing from the Plains of Moldena. They spotted Falender on the map and thought it might play a part in their history.
