In Character Flyer

During the recruitment process, this is what you would see IC as a flyer hanging around various major cities. Your character is to contact the character of a recruitment officer In Character via letter, and a meeting will be set up to get you into guild IC. This is only the case for those wanting to join The Keep. If you seek to join the Kingdom, they will contact or find you and offer their group as open to join.

Pamphlet for the Keep

So-you-want-to-join-the-Keep-e1533337580

This is the pamphlet you'd be given In Character when being recruited into the Keep. A recruitment officer should direct you to this page so that you can see it, and your character will actually learn about the Keep in full, and what's typical of this faction.
