It is amazing is it not, how you can grasp so many puzzle pieces out of the aether, and as if by magic they can form a puzzle.

She tends her brother's grave every second cycle, the movement of the Gates in the Arcade her clock.
She used to attend every cycle.

The first thing she does is check that nobody else came near it. Then she removes the weeds and tends the flowers. And finally she polishes the entire stand.

Afterwards she sits back and prays. Not to the Gods she's forgotten, but the ones she's learnt. Skolver and Vog, Profit and Loss, Sanctuary and The Swarm. She impeaches the former for protection from the latter and bargains with them too. And then she stands and takes her vigil, ensuring that none of the thieves steals his sword and shield.
She used to protect the other graves a long time ago, realisation that either the dead did not have anyone alive who cared for them or that she could not save them all breaking her in the end. And so she stands through the night, half-asleep and half-awake. Ready to defend the him.

Eventually she receives a Mission from headquarters. They need an extra body for an assault. Why, she does not know, when and why are given in an blind flash-copied email.
She used to seek out Missions.

She takes one last look at her brother's grave before placing the Trinkets and crowns around him. She hopes the thieves remain smart enough to realise that selling her brother's grave would be less profitable than simply taking the objects she offers them, as if they were gods that must be placated.

They are always Recruits, Apprentices and Squires, the ones who have finally dropped out of orbit after oh-so long. And thus they have Forgotten. She doesn't begrudge them for sins they do not know. But she always impales them through the heart and throws their corpse over the side if she catches them in plain sight.

Before she leaves she takes one last look at her brother's grave and the one around it. She sees Lionheart Blades and Exalted Shields surrounded by other Battle Stands acting like little islands in the ocean of empty plinths. Even those who have Forgotten do not go near those graves, as if they know that they are unworthy of being in the presence of something so powerful and just.
She used to feel like that too, she hopes that the thieves stay that way.

If she died now then the presence of her grave would deter the thieves from robbing hers and her brothers graves. But not forever. Only the Vanguards are allowed the weapons and shields that eventually become their grave markers.

And so walk off towards Haven, hoping her brother's grave remains untouched until she returns, waiting for the day that she can finally wield a Lionheart Blade and hold an Exalted Guard. For she knows that day shall come and when it does she will die with her mind at piece, knowing that even though her body may not be found, her grave shall shield her brother's for evermore.
