History of Chiasmus (triumph)

Overview

Chiasmus is a 10-point triumph with no in-game description or objectives in the data on this wiki. It shares its name with the Chiasmus mission in Riven's Lair (Dreaming City), from the Wishing All the Best quest in Season of the Wish.

Unconfirmed

I could not open a source describing this triumph's requirement, seal or reward. The Destinypedia page for the mission mentions no triumph, so how to earn it is unconfirmed. It may relate to the mission, but that is not verified here.
