The Academy Edition of the PHB contains first-tier content designed for levels 1-2

More content will become available to you when you reach level 3. When your character reaches level 3 then contact a staff member and you will have access to a new tier of content. They will show you another PHB at this time. In addition to being level 3, you must have RPed at least 3 times on 3 separate days to get the next tier. You are not allowed to view a higher-tiered PHB (that is, any version of the PHB but the Academy Edition) by any means other than staff permission.

Some things to look forward to in the next PHB:
