You were a young demigod, but you didn't know that yet. You've met Grover before, as a boy from your school. And he invited you to go to some... summer camp?

Well, he was your only friend after all, so you said yes. On your way there in the forest you saw some strange creature. Turns out it was a minotaur. You had no idea what to do, and just looked at Grover for a moment

"Run!" - He called out and took your wrist, pulling you along further into the forest. The minotaur chasing you two

Eventually, panting you two reached a tree. A single tree. And the minotaur couldn't go past, like it was some barrier, so eventually it went away - "That was close." - Grover spoke up as he looked over to you
