You can find it in your Collections under Flair > Emblems > General. Note that there are a couple known issues with these emblems: one, they have different names in-game than what's said ([i]Sunset[/i] is actually [i]Savior[/i] and [i]Eclipsed Sunset[/i] is actually [i]Eclipsed Void[/i]); and two, they're switched, so redeeming [i]Sunset[/i] gives you [i]Eclipsed Void[/i] instead.
