Since Makuta makes Rahkshi armor from kraata by using protodermis, he must have a supply of it in a small pool or spring. How much do you think he has and where does he store it? I think that he puts the protodermis in containers and then stores them. I know he must put the containers in a very secure spot. He probably has some nasty beasts guarding them too. As for amount, I don't think he has that much, otherwise he would have alot more rahkshi battling the Toa Nuva. What do you think?

Protodermis appears in veins in the rock. He just took some and melted it, I wager.

There 's Protodermis every where. He probably found a vein or something. There's plenty of room in the underground.

I think it is probably back in the bohrok nest. The nest chamber is right behind his chamber in Mangaia

The IQ

Most likely under the Bahrag chamber where the Toa Nuva fell into the protodermis.
