KMS 1.2.221 - Black Heaven

I'm still trying to understand the connection between Black heaven and Suu&Orca, can someone explain it to me?

In Act 1, you have to go into Orca's inner world to help her regain consciousness/search her memory for information about Black Heaven. In Act 2, the only thing relating to Orca or Suu is Francis sneaking onboard Crystal Garden haha. I'll be uploading my recordings of the entire quest line in the near future, if you guys are more interested in those (there are some cool cutscenes from Orca's past).

I'm assuming that Suu will make his appearance in future Acts, Gelimer appears at the end of Act 2 at a meeting of the Commanders so I think he still has control over him.
