The Magisters Sidereal remain one of the most important groups in all of Dragon Age history, even among recent events in Thedas. Dragon Age: The Veilguard shines some new light on their actions, while also setting it up to play an equally important role in the future. The lore surrounding the Magisters Sidereal grows ever so slightly from game to game, but there's reason to believe they could play a huge role in the future - as of Dragon Age: The Veilguard anyway.
