No one really remarks upon him—or even really notices him. They're all watching Zei, who's standing at the edge of the water. He's taken his sandals off at some point, and is breathing slowly with his staff in hand while he watches the soft waves and waits for something.
The tall torches have been also set into the soft wet sand and a ways into the water, a short corridor of light leading to where the dead are: numerous boats and underwater coffins can be seen, the water mysteriously clear despite the mess the attack should have made of it. Clearly Zei is meant to walk to them and do—something.
And he does. He takes one step, then another, but he's walking on the surface of the water rather than on the sand. This becomes clearer and clearer the farther down he goes, until he's past the torches and just standing there amidst the boats and coffins.
And then there's drums. Except—no one is playing them. And the voices start singing—except it's no one in the crowd. The song comes from all around them, but mostly from the direction of the water, where Zei slowly starts to sway in time with it. As the music picks up, so do his movements, and he's effectively dancing with his staff in hand, swirling in place as the water stirs beneath his feet.
And finally, the dead. Wisps of blue and white light, ethereal flame emerging from within the boats and coffins, from within the corpses. They grow in number the longer Zei does this, and start surrounding him before spreading outwards and upwards, zigzagging between the people still alive, disappearing off into the sunset sky.
And the people cry. They finally let themselves mourn, finally stop holding their breaths now that the rites are underway, now that they can see that at the very least the creature has not robbed their loved ones of peace. It happens almost at the same time for everyone, all of the villagers breaking down in tears or falling to their knees or wailing in their despair.
Zei just keeps dancing, his face a mask of concentration, and the dead are Sent.
