Duston is a member of Chaldea Security Organization in Fate/Grand Order.

Duston was a physicist who studied cosmic rays and worked on particle accelerators, scraping by to make ends meet. He was recruited by Marisbury Animusphere as an engineer for Chaldea fifteen years prior to the destruction of Chaldea at the end of 2017. Skeptical of Marisbury's words, he eventually agreed to take the position due to Marisbury's passion and earnestness for the project.

Duston has a dislike of Olga Marie Animusphere, viewing her as incompetent and constantly angry. He does think she held up well with everything despite her personality, thinking that they should have been more considerate of her circumstances and feeling sorry over the current state of Chaldea as of Goredolf Musik's takeover. As a normal human, he dislikes when "upstart mage jerks" make particular comments. He has come to view Chaldea as his home after spending fifteen years there.

A seventh Singularity has been discovered in ancient Mesopotamia in the year 2655 B.C. 
 
The land of Uruk, governed by the wise King Gilgamesh after he returned from his quest for immortality, was grand and prosperous until three goddesses and countless Demonic Beasts appeared. These enemies have brought Uruk to the brink of destruction. With a Rayshift—a method of traveling across both time and space—Fujimaru and Mash journey to the land of Uruk, where they encounter the fortress city of Uruk and the Absolute Demonic Front, where a terrible battle against the fearsome onslaught of the Demonic Beasts rages. There, the citizens of Uruk, who live their lives to the fullest despite facing an existential threat, continue to fight for their future. Deities and Demonic Beasts attack with terrifying force, and mankind pushes back with all its might... This is the era where humans and gods are destined to part ways. 
 
Fujimaru and Mash, the pair who have fought through all six previous Singularities, embark on their final battle.

The Lost Room.
A place where you can see what was lost, or maybe what will be lost to you in time.
Existing in the innermost part of Chaldea, it is the boundary line between dream and reality where the light of the moon shines through.
Produced by the Chaldea Summoning System, the room holds a small number of worthwhile benefits to enjoy.

After battling their way through all seven Singularities, the Chaldea Security Organization has finally arrived at the endpoint of the Grand Order: The Final Singularity, Grand Temple of Time: Solomon.
 
Now is the time to defeat the root of all evil, Solomon, the King of Mages. Now is the time to reclaim the future.
 
With the final operation looming large, Romani Archaman considers the choices he will soon have to make, Mash Kyrielight dwells on life’s limitations, and Fujimaru prepares to receive a new Mystic Code.
 
All their many encounters have led to this moment as Fujimaru and Mash at last embark on their final operation...

Miyamoto Musashi... a strange woman encountered in the minute Singularity. The concept of Pruning Theoretical Phenomenon... and a being who continuously warps from one world to another...

A new story unfolds after Musashi reappears and reunites with everyone at Chaldea. The time has come for the Seven Duels of Swordmasters to begin.
 
Note: This is the adaptation of the Epic of Remnant Chapter 3 from the mobile game, Fate/Grand Order.
