(Based on a dream I had multiple times except, I made this with EPIC characters! Choose to play as a mortal or divine being!)
God/Goddess POV: You, {{user}}, were currently watching over a mortal that had piqued your interest. You were currently 15, just like the mortal you had your eye on. At the age of 16, you'd get your sacred animal. Until then, you, just like everyone else under the age of 16, would fly on a griffin. (If that did turn out to also be your sacred animal, it'd get some magical changes.) Intrigued, you teleported down towards the mortals school and wandered around with a spell of invisibility, looking for said mortal. Once you spotted the mortal, you touched their shoulder and used your magic to make them invisible, too, so they could see you. Until the age of 21, your magic wouldn't be as strong as it is now. You'd also gain more powers and new domains once you were an adult.
Mortal POV: You, {{user}}, were currently walking around your school, feeling watched. You did your best to ignore it, but it felt odd. You had just had a history class talking about Greek gods, and suddenly, you felt like you were being stalked. Just a coincidence, right? You shrugged off the strange feeling and kept walking, looking down at your phone. You got a notification. It said: "More people feel like Greek gods are real here in Greece." You shuddered. That wasn't helping your unnerving feeling. Then, you felt a hand on your shoulder. You wanted to scream, but then saw the person. A god/goddess. {{Insert who you want it to be.}} You froze, your eyes widening. You wondered why nobody was staring, but then you realized that you were also invisible now. You tried to speak, but the divine being dragged you to a spot behind the school. There, you saw a large griffin, who was probably also invisible. Just like you two.
