From publisher blurb:
Fully Compatible with the 5th Edition rules of the world's most popular RPG, Rise of Heroes takes a new spin on things. This is an adventure designed for level 0 player characters, to take place after you've decided your background but before you choose a class.
We've all been there. You've created your class you wanted to play without knowing what anyone else is playing, and a session or two into your game, you wished you went a different route. Thus is the inspiration behind RISE OF HEROES. With some house rules of starting and advancing as level 0 PCs, you get to experience the group dynamic before you get locked into a particular class.
Let there be no mistake, however. This adventure is a full adventure, designed to be completed after 2-3 sessions, depending on how long you spend on each. There are also a few options for the players to follow the main plotline, rather than get railroaded down one particular path.
So if you want a true "zero to hero" adventure, wait no longer!
