The discs are the least of your issues regarding this character. You've only altered the minor issues and not the fundamental problem with the character submission.
This is an RP. Things are going to be different than what you've experienced with Bionicle in the past. You have to understand that not everything you know as a player is going to apply.
And to be honest I believe I have answered your questions to the best of my ability to avoid spoiling what I have planned.
Kongero Nui hasn't had any Toa before. You want to explore anything significant? Roleplay it out. You want to talk to NPC's? Write and roleplay it out.
