The Shields of the Sorrowfell initially met this tiefling in the Black Moor, working as the boatman for the Terrible Old Man. They left the Black Moor swamp and thought no further of him.

However, several months later, they encounter two tieflings, both identical to the boatman, guarding Morana the Forsaken’s portal in Barony Aalsburg. When killed, both collapsed into mirror shards and scraps of flesh resembling onion skin.

Clearly, something strange is afoot. Perhaps the Shields ought to reflect on their first encounter with this creature.

The Shields encountered several more of these tieflings beyond the Far Realm breach in the Chasm of the Cogitovore, including one of them that potentially appears to be the original copy.
