   Summary

   “I’m Kaveh. This delightful individual-” He gestures across the table. “-is Alhaitham.”

   This seems to catch Veritas’s attention, as he raises a brow and cocks his head to the side, studying Alhaitham with a curious gaze.

   “The Grand Sage?”

   “Acting Grand Sage.” Alhaitham corrects.

   The conversation continues. Kaveh insists that he and Alhaitham join Kakavasha and Veritas’s table. Kakavasha and Alhaitham find themselves on one side, Veritas and Kaveh on the other. Plates of steaming hot biryani are placed before them, accompanied by their drinks of choice.

   Or; A crossover Au in which Teyvat is on the Star Rail map, and a chance meeting between two pairs blossoms into something more.

   A slow-ish burn with multiple pairs into an eventual polycule, this fic explores flirting, sexual desire, open relationships, and enough fluff and romance to rot your teeth out.
