Kalpis
Nico stares at the vase in front of him. "It's not a vase Nico! It's a Kalpis." Percy tells him before leaving no long after. At first Nico really just doesn't understand why Percy would give him this. Then he does some research, a kalpis is used to carry water. Water. Percy's element. That's when Nico blushes. It's similar to the jeweled ring he gave to Percy not very long ago. An exchange of elements is significant to demigods. It's the purest sign of trust. The he turns the kalpis around admiring the decorations that adorn the sides, until he notices and inscription. To my Nico. - Percy J. He made this. Percy made this for him he realizes. He gently picks it up, smiling as he carefully sets it down on his shelf.
