How to add contents on forced user login page for anonymous users

Hi, i hope unlike acquia, someone will hear my plea here.

I just want to know which page, view or context do i need to touch inorder to add some few contents like mission, objective etc on the page where my anonymous users land up before logging in.

I am redirecting users to forced user login page using the built in option. Pls somebody guide me (and m not talking about the homepage or frontpage)
