From BZPB Wiki

BZPower is a LEGO fan-site focusing on Bionicle, Hero Factory, and other "constraction" lines. It is also where BZPB originated.

In the RPG

In BZPB, BZPower was the home of the Users. It was once part of the Internet Dimension, but it was turned into a planet when it was transplanted into the Original Universe. It was ruled by Black Six and the Staff until the Battle of the BZP Staff HQ, when Black Six was badly injured and replaced by Tufi Piyufi.

The planet suffered attacks by Blackout and Unicron, causing many areas to be completely destroyed and many others to be heavily damaged. Most of this damage has since been repaired.
