The party must find a series of red gemstones and place them in the eyes of statues to acquire the code to access the room where Odin is fought. After the player opens the door, the player may leave Centra Ruins and return to get more time to defeat Odin. The player must solve a few puzzles within the time limit, obtain a code and open the door to where Odin awaits. Once the ruins are entered, a 20-minute timer will appear, counting down until the player defeats Odin. Odin is acquired from the Centra Ruins, an optional dungeon on the Centra continent the player can reach once they gain access to free-roaming sea travel.

He is one of the Guardian Forces who speaks to the party. With it, Odin is able to cleave through almost anything in one hit. His face is bronze-colored and he wields a long blade known as the Zantetsuken, which translates to 'steel-cutting sword'. Odin wears dark form-fitting armor with large horns and gold details. Odin is a warrior who rides a six-legged pale gray horse with pupilless white eyes and brown mane and tail.
