I think I know where thematoran find the Tol. go to the back page of comic 10. look closely at the board game. in the middle of the board is a gateway shaped like the MoL. entrance of ToL's lair.

or it could be the entrance to makuta's lair.

or they could be the same.

They could be the same, yes, but isn't Makuta's lair under Mangai? I thought the only ways to get to his layer were Kini-Nui or around the Volcano.

Highly doubt it. Looks more like a goal of a sort involving finding the Avohkii. I mean he is in hiding right? If that was real than Makuta could find him easily.

Hmmm..interesting.Thiscould use some reacherch.
