- Karzahni’s madness makes sense, so I don’t see too much of a problem with it.
- I absolutely want the Elemental Gods (Nuva) to be made before the Matoran, based on what you said. If Makuta hated the idea of the Matoran becoming sentient, there is absolutely no way he would EVER agree to having powerful guardians created with sentience (unless Ekimu does it secretly behind Makuta’s back, which could spark the War of the Brothers, nixing the purpose of the Lightning Tribe).
The only way it makes sense is this: the Nuva are created sentient, but their unique nature prevents them from ever harming the Brothers or the physical world, while the Brothers are capable of harming them. The Matoran are created, but Makuta is against granting sentience to Matoran due to their nature (they are capable of harming the Brothers, albeit with little to no effect). The Nuva are able to channel their power into hosts (turning Matoran into Toa), which allows the Brothers to be defeated with relative difficulty. This could prompt the Brothers to create massive guardians as a countermeasure, based on what Karzahni sees in his visions, but the Toa still win.
That’s just how it makes sense to me, anyway.
