From what little I can read it looks like this:
Lusamine is thanking him for...something. Probably also praising him for his work.
I can't make out what she's saying about Mohn though.
I think from what we know about Faba (being self-centered and wanting to be the head of everything), he probably pushed Mohn into the wormhole in hopes of taking over his place.
Having to work under the woman he widowed I imagine he's rather guilt ridden.
Again though, I can't read too much of it.
