Keys for a door which none should open

we all know that the omniverse can never be sane ..it is as if it demands the utterly preposterous and impossible ..the unknown shall never go away and thus they exist to protect all of existence from the collapse . yet when the ever ascending man and the church of broken god under mekhane's trance create a key which a specific user can use to summon the vast hyperversal and omniversal horrors lying in their own multiverse inside the tree of knowledge into a lesser dimension which is outside the tree and previously unheard of even by the wanderer's library or SCP 343 and then sends it off . those who fight in the shadows so that we may live in the light have to come forth and sign an unlikely alliance with other groups of interests to contact the individual who shall wield the said key . For she is...the chosen summoner.
