Florfindyn lived in peace with his people in the Misty Forest until 1363 DR, when, at the start of the Second Dragonspear War, the Hordes of Dragonspear attacked the forest. During the fighting, Florfindyn was defeated and captured. The cornugon Vesarius recognized him as a prince and took him to Dragonspear Castle.
There, Florindyn was tortured in order to gain useful information Baazka's plan, but with no success. He even managed to escape from the castle, despite being reduced to a mindless beast. Finally, he was saved by some adventurers leading the allied armies.
