The rulebook says 10sp per km, and the distance from Jrustela to Zistorwal is 2000km, so should it really cost 20,000sp to get there? I'm thinking that's a little on the high side. There's working passage, of course, and the party did just save the ship from a giant crab attack. Well, the sorceror did it single-handed while everyone else bounced off its armour except from one high-rolling Naginata hit.
