I would be interested if it's a pick of poisons.
Ending A: Side with Gaspard
King Gaspard proceeded to reform the chevalier orders of Orlais and crack down strongly on infighting. Many nobles were executed for their crimes and a new regime based on honor and tradition replaced the Game. King Gaspard's reforms to the military were the most memorable, though, as he began employing elvish scouts and units aside the main army. For some, this was an improvement and Orlais' elves for the first time started to consider themselves as Orlesians. The first kingdom Duke Gaspard invaded was Fereldan but it would be far from the last as the flag of Orlais became planted in many new lands.
Ending B: Side with Celene
Empress Celene instituted a new Golden Age in Orlais based on intellectualism, art, and prosperity. Peace occurred across the Empire as she brokered treaties with many of the surrounding lands. The Empress never married but named a suitable line of secession through a series of cousins which managed to avoid chaos following her death at a ripe old age of ninety-six. Unfortunately, the Empress Celene was forged to renege on most of the promises she made to regarding civil rights within the Empire. While the lot of the Orlesian peasant improved, the life of the Empire's elves became much worse. Purges of Alienages, laws against intermarriage, and heavy taxation caused many to move to nearby Fereldan or Nevarra.
And there's no third option.
