I know how Noah can get the heart of Reality. By integrating all of reality into him like that Emperor from the past age tried to do and failed. If Noah successfully does that, then he should get the heart of Reality. Also Iām guessing everyone here is going to know that he is the dimensional inimicus as he is going to devour the entire dream dimension and add it to his infinite dimension. Thanks to the Tribunals, they made it much easier for him to do so.
