Mattias is a character in Octopath Traveler. He is a trader with the Leoniel Consortium and is the antagonist and final boss of Ophilia’s story.



Mattias has medium-length sandy colored hair and wears a blue coat with fur trim with a light brown shirt underneath. He also wears black pants and boots.


As a merchant, Mattias puts on a modest and kind personality. He is nevertheless eager to call others’ faith into question, believing that people suffer because the Sacred Flame turns its back on them.

Under the surface, Mattias possesses an incredibly twisted sense of self-righteousness, thinking himself the “one true Savior” destined to resurrect Galdera so that he might gain his power. Driven by his hatred of the Sacred Flame, he has wholly dedicated his life to that goal. He is skilled at finding a way into people’s hearts in order to bend them to his will, and will not hesitate to use lies, murder, and manipulation to accomplish this. He does not believe in love.

The following section contains potential story spoilers!

115 years prior to Octopath Traveler, Mattias, once called "Matthew," was a priest of the Sacred Flame in the Frostlands. The village was struck by lightning, starting a wildfire. Despite his fervent prayers to the Flame, countless lives were lost. This caused Matthew to question his faith and eventually reach a "revelation."

That same year, Matthew gained 100 years free of aging from Lyblac and established the Obsidians alongside Simeon. He sought to weaken the Sacred Flame and allow more of Galdera's power to exit the Gate of Finis, which would grant him more power.

Over time, he slowly cut his ties with the church and began using Galdera's power to bring about miracles. He established a cult following as the Savior of Wispermill in order to gain access to the altar in the Ebony Grotto. He worked his way back into the church under a new identity, as the trader Mattias.

In the final step of his plan, Mattias murders Archbishop Josef with poison provided by the Obsidians. Upon the Archbishop's death, he plots to take advantage of the next Flamebearer, Lianna, using the despair of her father's passing to manipulate her into acting as his vestal in order to bring Galdera's flame to Orsterra. He convinces her to drug her adoptive sister and acting Flamebearer, Ophilia, in order to steal Aelfric's Lanthorn.

While conducting the ceremony at the Ebony Grotto, Mattias instructs Lianna to pray to the Flame with her greatest desire. His followers begin to collapse, their purpose being sacrifices to the dark flame. He is soon confronted by Ophilia, who was discreetly freed by Lianna, and is defeated. As he lays dying, he curses Ophilia for loving her sister too much, and wished she never took her place as the Flamebearer so his plans would succeed. Following his death, he is forced to exist in a dark limbo with no light.

A journal containing his thoughts after death can be found at the Gate of Finis. He cannot understand how Ophilia was able to stop him as he truly believed he was the destined savior, and despairs about being trapped in the void.
