A lone Destiny player (or at least only one outside of Bungie) has acquired the Fate of All Fools exotic primary weapon which it seems will be off limits to the rest of the game's community until a future DLC pack.
The weapon was sent by Bungie community manager Deej to help a player whose doctor suggested the game could act as a form of therapy. On Reddit, user Bkbunny 87 commented:
"Yesterday I had a post talking about my husband and his Doctor recommending Destiny to serve as a form of physical therapy for him following several brain surgeries. This community was amazing, and raid groups are being organized for him out of all the people who offered to help him.
"But just as amazing, Deej contacted me and has sent my husband a care package from Bungie that is on the way. Then this morning, a message from Deej told us to have my husband check with Tess the Post Master in the tower. Lots of screaming ensued.
"He has been sent the exotic gun Fate of All Fools, a solar primary that looks like it will be available in future content."
What makes the weapon so interesting is that it is an exotic primary gun with solar damage.
