Edward fights a Sahagin alone when he returns to Kaipo, suddenly jumping out of a river during the middle of the night. Despite the enemy's incredible HP, only three attacks must be used, each triggering a battle-message, the final ending the battle. Such messages are said by Anna's ghost to encourage Edward. The Sahagin is a random encounter in the Underground Waterway, though it is of no threat to the party.
Sahuagin (often misspelled or transliterated "sahagin") are fishlike, monstrous humanoids that appear in the Dungeons & Dragons role-playing game.
