Well, i'd think it be best if the value of the contents of the treasure Griff has would be up to sable or crimson, couse I have no Idea how much 500,000 belly is in amount of treasure, and since its a condition set by Danni for story (maybe), I think it's best that you decide if it should all be payed right away or that we have some moeny to start of paying the debt (maybe pay marshal at least for the time being).
