What happened to the Masamune in El Nido?
After it was used in the conflict with Porre in 1005 AD the Masamune was stolen from the battlefield by an unknown person. Within the next five years (give or take) it wound up in El Nido – how this happened is not revealed. The first place it is seen is in a cave at the top of Divine Dragon Falls, on El Nido’s main island. Radius and Garai take it with them when leaving, whereupon Radius falls under the control of the sword’s malicious influence and kills Garai. We don’t know what year this happened, but it is presumed to have been between 1010 – 1016. The sword was discarded at the falls, but apparently an individual placed it on the Isle of the Damn because that’s where it was seen in 1017. Presumably Garai’s anger for having been murdered coupled with the Masamune’s amplification of negative energy had an effect on the island which caused it to mutate into an isle of bones, tar, and the undead. Dario and Karsh ventured to the island then and found the blade near Garai’s grave. Hist
