She tasks Quinn to travel to an old hopping point, hop through without dying, and return to her with proof of his success.  

  The hopping point is in a forgotten valley well outside Hearts' eastern border, surrounded by overgrown jungle and swampland.  

  He can only take Yahante, to ride and for protection, but Jasmine and Cayde must stay in the city.  Yahante can't hop through with Quinn, so they will have to make their own way back to Dasgarade on their own.  To prove he hopped through, Quinn has to [?]

  On the other side of the hopping point?  where does he go, how will he get back?  Yayyyy I fixed two plot holes in one!  So he hops to the bottom of the Ravine in Diamonds.  He didn't pack for frickin' New Mexico so y'know dehydration and heatstroke, fun stuff.  Someone finds him and brings him back to the kingdom, where Queen Opheliah is a little mad he intruded into her kingdom without her noticing. He explains how he hopped here on accident during his Hearts quest.  Opheliah gets this grave look in her face and explains the plot to unseat Queen Isadare, and her might is the only thing stopping them; take out the Diamonds, open the door to Clubs.  So Mary and Beligri plan to use the hopping point to hop over the border to take out Diamonds; they had thought the point led here and they were just using Quinn to test their theory.  So that's how Quinn finds out the plot and fixes the little problem of where did he go.  

  He does get injured, I'm thinking a painful gash on his bicep; that would really suck because its in the muscle.  Maybe throw in some head trauma?  But what injures him?
