Hello! I read the first two parts. They are both the prologue, so I would recommend condensing them into one part if you can. Prologues in general should be kept short.
English is my first language so I’ll try and give a little pointer.
In general everything (except for dialogue) should be phrased in the same tense. For long form fiction it’s typically put in past tense.
EXAMPLE:
Present tense:
He loves the silence.
Nobody knows why.
Past tense:
He loved the silence.
Nobody knew why.
Present: is, are
Past: was, were
I've never read a book that was written in the present tense. That doesn't mean it’s wrong necessarily, but past tense prose are more comfortable to read than present tense prose. English is weird.
The set up being an esper confronting the grave of the person he’s seeing the memories of is very interesting! It seems like he visits this specific grave often as well, which makes the reader question why. Leading questions are good to have in a prologue!
I’m confused by Cenric considering that history has been altered by his dream. If this is a legitimate possibility it should be much more concerning.
Overall the prologue establishes the setting very well! I will update this comment if I think of any other feedback as well!
Here is mine (I'm debating giving it a mature tag):
