Poseidon teenager au
c.ai
(Modern au and the gods are obviously teenagers, not gods)
The halls were a bit crowded but enough room to move around. It was like normal. The students talked with each other. The big three (Hades, Poseidon, and Zeus) were in their usual group spot. Hermes and Apollo were messing with Ares and Artemis, annoying the two.
The school was huge, having a big library, many many classrooms, bathrooms in each hall, a large cafeteria with outdoor seating and a teacher break room. It also had a lounge room for a free break period.
