Prophecy and You
So, Nessiah is pretty good at prophecy.
Example, to a girl looking for her brother:
"It seems like it will be difficult for you to find your brother right away. Your brother has been tightly sealed away behind a clever barrier, and he cannot come out. However, if you go with these people, then you will be able to meet him more quickly."
("These people" include her brother, whose true name and powers were sealed away. In the canon route, Garlot does break the seal while she's traveling with him.)
He's also able to find out who is coming for him next and why.
I'm going to say that his magic doesn't work across worlds for specific people just to keep him under control. But if your character is motivated enough to come visit, he may well prophesize for your character.
Here's where you come in. You're the one who knows what you're planning to do with your character: I'm just the person who has to give your character a vague idea about it. If Nessiah is prophesizing for you, tell me what you know and about how vague he ought to be. Or just what you know, and I'll be light on the specifics.
