Very Cool. I've not tried VASSAL before, I couldn't work out if there way a way of placing a character figure on top of map. I wasn't sure where cards went when you drew multiple cards.
Sorry for the late answer!
Anyway: to place your character on the map you simply have to drag-and-drop it onto the map. (the character figures are grouped together with the character cards, so you'll have to deselect the group and select the figure singularly)
When you draw multiples, they are similarly grouped in a selection. So you have to drag them to some place, then deselect and reselect the top card, when you move it you'll see the cards below it.
Hope this helps!
