Legendary:what is the name of xur's race Exotic:there are 2 fallen houses not mentioned ingame. What are they called

Legendary: I'm not familiar with any name for his race other than he represents the Nine. So the Nine is my answer. Exotic: The Houses Stone and Rain are those that come to mind, however I think there are small refences to each in game. Those are my honest answers.

The exotic one was spot on yes there subtle hints to these in game like variks' dialogue and taniks having the house of scars cloak As for legendary his race are the jovians

Respectfully, do you have a source that confirms the word "Jovian" to be a descriptor of Xur's race and not an adjective describing where he comes from (Jupiter). A human from Mexico would be mexican and a human from anatolia would be anatolia - but each are human. Ganymede, Io and Xur are all Jovian in the sense that they are 'of Jupiter,' however Xur is no moon. This being said; I do not think Xur is one of the Nine. I just want clarification, else I've been under a false assumption for Xur and the word Jovian as it relates to him. Also: more exotic/legendaries please.
