"How did you find tonight's Dares of Eternity, contestant? Was my performance of the ancient ritual of 'hosting' to your satisfaction?"
Xûr gazes at the shifting aspect of Starhorse. "It pleases the horse when I speak those sacred words…"
He hesitates. "…though I do not understand all that the horse asks of me. But there is much I do not understand."
He composes himself. "I keep another mystery, Guardian. I know of a key that will lead you to great paraversal riches. The astral steed will allow me to create this key for you if you dedicate yourself to its whims, as I have."
Xûr does not wait for you to respond. "Bring Strange Coins back to the impossible horse. This is the first step… and something tells me we are just getting started."
