Enron:
Do you know anything about alligators? Since long before, an influx of alligators came from Avellan in the east and settled on Alligator Island, began propagating, and covered the island with alligators. The name of the island was even changed to Alligator Island.
These alligators are so ferocious, even those from the castle couldn't approach them. So don't risk your life going after them.
(Ertheia classes cannot perform this quest.)
