I noticed a lot of people don't know the pledge, one of my huntresses, HowToBePolo101(Kate), suggested the idea of putting the pledge in the book.
So, the pledge is:

"I, (insert your name[I suddenly thought of Sadie Kane]), pledge myself to the goddess Artemis. I turn my back on the company of men, accept eternal maidenhood and join the Hunt."

And if Artemis accepts it, then you can join.

Also, this is Agnes talking :)
Cya before I get caught...
Artemis: THIS IS NOT YOURS.
Oops...
Bai.
