True. I mean the architect surely retains his memory and may want to get revenge on Jinwoo and Ashborn. He may have tampered on something to open those gates again and call on otherworldly beings since the monarchs were dead. Another thing, Jinwoo may have thought to use them, heirs of the monarchs to help. Since he took control of this 'system' the architect created.
That doesn't 100% make sense ngl. By definition architects design structures. In a sense, they themselves create. Its been a fat minute since I've brushed up on solo leveling, but he, in essence, created jinwoo, and in turn jinwoo whooped his ass. The story fits- theres a very large possibility that I'm wrong, but it the closest being we've seen to a creator i think
If you read clearly, the architect is just a designer for the system. He doesn't have authority over it cus he used the power of Ashborn for his designs to come alive. So it's kinda like how an architect designed things but an engineer make it into a reality (if that makes sense).. Without the power of the Shadow monarch (engineer) then the design cannot become a reality.
Now about the absolute being thing, it's been mentioned in earlier chapters and also already explained in SL that the rulers rebellion caused their creator to die....
And a note, the architect doesn't have that much power. He's just a servant(?) For the monarchs
this creator.. is he/she/them the architect? i mean, the world reset right? so he/she might be alive. where are the silver wings dudes?
