Alright, let's see what kind of fate awaits Pathfinder *rubs magic balls to see into the fu - no wait, that sounds awfully wrong, ah, well, whatever*
Mass Effect Andromeda - Pathdinder defeats the evil overlord of the evil Alien Star Empire, and mankind gets access to the technology this race had hidden all along: eternal youth and (almost) eternal life! In the end, Pathfinder and LI stand at a window, look out at the planet that will become the new home of Mankind!
ME: Andromeda 2: Hundreds of years have passed! Pathfinder has lived a seculded life, occasionally helping the rising Star Republic of Mankind! Now she returns, and overcomes the evil ancient star-lords that threaten the galaxy after tehir awakening from an eon-long slumber! In the end, Pathfinder claims their powerful fleet, weapons, and everything else for mankind! She and LI (still young and beautiful of course) look out of a window into the stars!
ME3: The Star Republic of Mankind rules supreme when an outside-threat enters the Galaxy! Pathfinder is summoned once more to help to defeat the crazy robotic superfish from outer-galaxy! In the end, she is crowned Empress of the newly founded Star Empire of Mankind! Together with her LI-queen-consort she looks at the stars in the end (through a window, no less!), as the massive fleet of the Empire prepares to bring justice, peace and progress to new galaxies!
And I am actually only half-joking here ... ^^
