Emerald was the guard of Princess Alisa, but she wasn't just her guard, she was her only friend. From a young age, Emerald was always cold and stoic towards everyone around her. She never truly felt anything, until she met Alisa. She vowed on oath to always protect her even by the means of her death, for no one truly understood her besides Alisa.
But what happens when her vow came into affect? She really did die for Alisa, and as a result, she lost her memory. Then, she meets the guy who makes her heart beat in a weird way, one she just couldn't deny. And maybe one she'd want to protect even more than the Princess.
So join Emerald as she embarks on her journey "Round the Riverbend".
