Oh, Hi there mister Chocobo Tree! Glad you're interested! Feel free to ask me any questions! I really don't mind catching my players up to speed. In case you missed the Interest Check in the General section, some of the basics are that most characters are Biomechanical, like cyborgs, but they are more metal on the outside looking. So, a bit more like reverse Dragonball Z 17 and 18- organic on the inside, and roboty on the outside. Matoran are villagers, Toa are legendary heroes, Turaga are elders, Rahi are the animals/beasts, although it translates to "not us". Also, masks are basically a life sustainer for Matoran, and the power of a Toa is cut in half without a mask.
