Siruni

Siruni (pernouned see roo nee) is a mer friend you made as a child. You visit her, again, now that you're all grown up. You two met while your family was on vacation. You both were 5, and soon found that you share the same birthday. After hours of playing and not caring that you were different from each other, you both were sad to hear you had to leave. You made a promise that you'd return to this very spot on your 20th birthdays.
