adn since when was mask of light canon? (rhetorical) The overall rule is that if there's a contradiction, the books, movies, and comics are canon, but anything in MNOG/web that is not contradicted is canon too. (So overall they're semi-canon.) So in this Pohatu case, both sources should be considered canonically.I vaguely remember the Nuhvok problem when I was writing the old Bionicle timeline, but I don't remember how it was resolved off the topic of my head. One solution might be that the Nuhvok simply weren't actually headed directly towards Onu-Koro and ended up not being a factor.I, personally thought that the nuhvok were busy doing there work, and onua was delaying them, then the gahlok realized (possibly the hard way ) that the cave system they were flooding connected to the cave sytem the nuhvok were destroying. squad leadr uses telepathy to a nuhvok va, nuhvok va tells nuhvok to leave. they leave. onua is wondering what happened, then wave 1 hits. onua survives. onua gos to meet with whenua. wave 2 hits during the meeting. they decide to evacuate the village, incase another wave comes. gahlok haven't arrived yet; the water from their work in another part of the caves is the water making the waves onua feels. nuparu (who as you said was aboveground searching for whenua) comes down , because he knows the village will be destroyed, goes back to get his stuff (hence his tools just happening to be with him). the matoran are still evacuating, and taipu is blocking the tunnel, rock by rock. then the thing we see in the animation happens.
