Major Stridan held a significant rank inside the First Order's military, which itself was a political and military group that arose from what was left of the fallen Galactic Empire. Functioning as a pilot, this major once piloted an Upsilon-class command shuttle. He was recognized for his commanding and powerful voice.
The character of Stridan initially appeared on a card included in the Upsilon-class Shuttle Expansion Pack, which Fantasy Flight Games made available for their Star Wars: X-Wing Miniatures Game back in 2017.
