Mass Effect: The Other Shepard

(DISCLAIMER: I DO NOT OWN MASS EFFECT OR ANY MATERIAL RELATED TO IT. THIS STORY IS JUST SET IN THE UNIVERSE OF MASS EFFECT AND CONTAINS SOME OF THE CHARACTERS FROM THE TRILOGY OF GAMES BUT MOSTLY CHARACTERS AND PLOTS OF MY OWN.)
After helping his older brother, Commander John Shepard, defeat the rogue Spectre Saren, his geth allies, and the Reaper Sovereign, Lieutenant Alex Shepard was inducted into the ranks of the Spectres after risking his life to defend the Council by boarding the Destiny Ascension and repelling geth boarders. After becoming a Spectre, he is given his own vessel, a prototype frigate created by all four council races called the Night Lance.
He even builds his own crew and squad, comprised of members of both Council, and non-Council races. And his missions could give even his brother a run for his money.
