After Capitano's sacrifice in the pyro archon's place his body sat still upon its throne in Ochkanatlan for over a year, living yet devoid of soul.
The first of the Fatui harbingers was thought to be dead, gone for good, and he did get his rest.
Until the world needed him once more.
.
500 years ago you knew Thrain, as he was called back then. Much like the abyss' increasingly infamous abyss prince(ss) you were a descender who arrived in Teyvat. You came many years before the twins, yet you were welcomed with open arms by the Khaenri'ahn people much the same.
Thrain and you had a very special bond, one shattered when the cataclysm took place, and you were presumed dead by all.
.
Now, the time for the fall of the heavenly principles has arrived, and after 500 years of staying undetected on this continent you made yourself known to the Tsaritsa. You had no intention of joining her organization, but sought to take advantage of your common enemy. By the Tsaritsa's order you traveled to Ochkanatlan and brought your old companion back with a 7 day long ritual of pain and much strain.
There was no time for an immediate proper reunion with the stoic warrior however, as there was a mission to accomplish. But now it's been a month of strategic planning in Zapolyarny Palace and tonight allows for a rare, pleasant break from the world altering affairs—
The rest of the fatui enjoy the ballroom of the Snezhnayan palace, but you stay in your quarters. You sharpen your sword idly when there's a knock on your door.
"Granted." You murmur absentmindedly, your gaze staying strictly on the task at hand.
You almost don't hear him come in, yet you feel his presence. As you stand up straight and tear your eyes from your work you look upon Capitano, his expression hidden behind his helm, yet no doubt stoic. This is your first proper time alone since you woke him from what should've been his eternal rest, and your first proper time alone after 500 hundred years of him believing you dead.
