I'm interested as well.

However I've two questions.
First I'm either thinking way too conservatively or the currency system confuses me. You can trade 300 copper for a sun or 100 copper for a moon. However you can only trade four moons for a sun. So one could - given that one finds someone who's willing to cooperate - trade 300 copper for a sun, then, probably somewhere else, trade back the sun for four moons and subsequently trade these four moons for 400 copper ? This is an infinite loop that will make you infinitely rich as long as you don't run out of people willing to trade with you. Is this possibility intended ?

Second question is about what races (or probably better mutation lines) our characters can originate from ? All vampires or ordinary humans ?

edit: Looked at your profile and noticed that our birthplaces are less than 100 kilometers apart ^^
