Lore bit:
The istener fruit is a highly prized delicacy amongst the Valkyrians. This sweet fruit is loved by the race, thanks to not only its sweet-citrus taste, but because it contains raw sunlight, a necessity in the Valkyrian diet. The istener vine uses sunlight in such a way that instead of converting it into energy, it stores the light inside its fruit. Thanks to this, Valkyrians enjoy a tasty and energetic snack that fills them with sunligt during the summer seasons.
Emily in particular cannot, and I repeat, Cannot have enough istener juice, or anything istener fruit related. One could say she has a problem… but we won’t.
