Might as well write a new post, figure Scalpel and co will take a barge down the river until they reach somewhere near Fort Horn and then take the road through Canterlot. I may have him end up in Star Harbor trying to find a boat to Trotpoli when our old salty seadog of a god arrives, who knows. He'll probably be intrigued by the vault invasions (if those rumors haven't been hushed up) and maybe make his way to finding Arcon, but I'll cross that path when I get there.
