You fail to acknowledge a few things in your endevour to put forth your wisdom of the Kami and your beliefs on others:
Like the Karavan, the Kamis travel freely through the lands of Atys keeping endless watch and endeavoring to make pacts with laudable homins in exchange for deeds done.
Both the Karavan and the Kami can travel freely throughout the lands, at least for now.
And although in the legend it states:
The Kamis have been placed on Atys to watch over the planet and defend it against anyone who might threaten to break its natural balance.
It does not state that the Kami were originally from Atys, only that they were placed on Atys to watch over the planet.
Also, it was not the Kami who are here for the Homins, as per the legend:
Jena sent in her disciples, the Karavan Guardians, to establish the homins in different parts of the planet so that each race would have a role in its conservation.
Jena brought forth peace and propser to the Homin kind, all of them, so that we could all work together in conservation.
Low and behold, along comes the Goo and the Kitin once again, 2 more problems to the Homin Kind, now, where as the Karavan seeks to defend the Homins and allowing them to construct weapons and armor to build defenses, the Kami use there power to scorn and punish the Homin for trying to defend themself.
The Kami have mislead many Homin to there cause, and unfortunately, even you have fallen prey to there lies and deceipt.
The Kami have allowed the Goo to further prosper and they also have allowed tribes to get a foot hold and stop the Karavan and the citizens from building defenses against the Kitin.
You tell me, why would we trust such devient creatures when all they have done is try to tear down out ability to defend ourselves, this can only lead to the end of all Homin.
If we can eradicate the Kami presence in matis lands, this will allow us to once again increase our defenses against the continued onslought of Kitin, and prepare ourselves to fight against the continued growth of the goo, that even the Kami have ignored.
The Kami are allowing the goo to transform every living thing into monsters, why would anyone want to follow a race that allows such attrosities to occur is beyond my comprension.
