DORONAI NUI

The Doronai Nui is our BIONICLE G1 D20-based tabletop roleplaying game.  Originally released in 2018, we've continued to update and expand upon the original system over the years, building toward what we hope will eventually be a fully-featured representation of the BIONICLE universe.
Currently, the Doronai Nui (version 0.12.0) offers over two dozen playable species, over 100 Kanohi masks, and the sixteen primary and secondary Elements.  It also features subsystems for crafting, building weapons, vehicles, structures, environments, and more!  We also offer a smaller version of the game, the Doronai Kofo, for those seeking a less complex system.  We periodically release updates to the game to fix bugs as well as add new features - in order to get the most up-to-date game experience, make sure you've downloaded the latest update!
The system is still in its beta stage, and we welcome feedback on how you think it could be improved.  Found something that doesn't work as it should?  Let us know!  You can get in touch with us via the email address listed in the footer, one of our social media pages, or our Discord server.
The game, its updates, and expansions are all provided for free, and can be downloaded from the pages linked below; the game files are available to download both as a single ZIP bundle or as individual PDFs (coming soon - the site is still under construction!).
