Backstory[edit]
When Daxter fell into a vat of dark eco, he was turned into an Ottsel (a bit like an otter and a bit like a weasel). He and his best friend Jak seek the help of the Green Sage Samos, Jak's guardian and mentor. But Samos tells them they must seek Gol Acheron, the Dark Sage, far to the north. With the help of Samos' daughter, Keira, who is a master engineer, they do so. On the way they find many artifacts and temples of the Precursors, an advanced civilization which disappeared long ago. When they find Gol Acheron, he has been driven insane by dark eco and plans to destroy the world. Jak and Daxter defeat Gol Acheron. but Daxter never does become a human again. After their victory, they discover a Precursoe device called a Rift Gate and a Rift rider to activate it.
