The Background Generator is based on Central Castings: Heroes of Legend. By game designer Paul Jaquays and been updated for 5th ed DnD. To have a little more dynamic background. I have taken things out or adjusted for my campaign. So if you're reading this and your not player feel free to use. Little about Heros of Legend character creation system. This is out of print book for Advance DnD that been widely coventated by players and DM's like and used to this day. Even 5th DnD background system is inspired by this character creation system. However this goes a lot more deeper to flush out fantastic character. This books been out of print since late 1970 and is hard to find. I found my copy at half price books collection cabinet for 200 bucks. There are PDF online but even those are hard to find. The second edition is so rare that even finding image of the cover is hard. There is few copies sold online but last time I looked it up it was 1500 dollars. Warning DM should look over each set up before approved the background since really lucky rolls can created overpowered PC even at starting level. The goal is to create interesting and dynamic backgrounds for royal play not munchkin stats . If your not comfortable to tell your players no, or skilled enough to adjust your game for the power influx I suggest you not used this.
