when spaceship first time stay on tevat space. the hp come out from it as space continue thier journey maybe ai don't want traveler to get inot mess and give them a more compiatable world. hp defeated the dragons. and the take a contorl over the world.

then they make humans as planet become more compatible. but there was a problem humans trying to seek power and as a result this world will be also destory like traveler previous one. so hp genoside the kenniah so they cannot seek the truth of the world.

but as traveler ship returning to tevat. kenniah people perform the ritual and summon the sibling. as they called us hope.

you rember the scene when our travler asked the sibling "what this have to do with us"

and sibling replied "this is all about us"
