(still wonder why the braindead nobles didn’t build rich person land on it, like come on you idiots that shits peak strategical land not to mention you can separate rich from the poor better by making it a hike up to the rich guys)
You could make it connected to Poseidon as well, either intentionally or unintentionally. Since his shrine is on the island, the trainees (Meat Morsels hehe) feel more powerful after they drink some of the shrines holy water, or take a swim in it, which is why they’re able to push themselves so hard. They could know about Poseidon’s power and intentionally chose the mountain for that purpose, or it was a coincidence that allowed them to be more powerful.
bro i originally thought it was for orthrys too
(still epic suggestion tho, both the anthill and mt.orthrys need some content, orthrys is literally my favourite place because of the scenery and layout but it really does need some more content, maybe animals?)
