I recently discovered this fellow in my Grimoire
Has he made an appearance in the game yet? I haven't come across this individual yet, so is his appearance triggered by story events?
The wiki says
Xûr sells extremely rare goods in exchange for Strange Coins and only appears on weekends. Xûr's coming and going depends on the planetary alignments.
This seems inconsistent, does he appear every weekend or just when he (Bungie) feel like it?
Xur appears at 7am EST on Fridays and leaves 7am EST on Sundays. His location has changed each week, but he's usually easy to find if you wander around the Tower for a few minutes.
He sells 1 piece of exotic armor for each class, 1 exotic weapon, and an exotic engram that is guaranteed an exotic (for a random class).
He also sells various upgrades for your sparrow and exp boosters for your weapons.
The main currency he accepts is strange coins, but you can buy the exotic engram with Motes of Light.
He appears on the weekends in random places in the Tower. You can use the map on the companion app to see exactly where.
