I keep getting reminded that "gold has been placed in your keep". I don't see any improvement in my finaces I know it is Nalia's old castle and when I go back and talk to the major domino,he just says hi..and no improvement in my finances. i looked around once to no avail. Am I blind or just stupid?

You are a little bit of both.....

Ask him you need to collect what gold you have collected so far, he should tell you where he keeps it.
