Ok, I've looked around the map lots, the whole map so far available, ended up coming across two swordsman skill caves and give up: I'm past the bit where you get the wine for the pirate, and you get the raft as a reward. I've gone to the cave where Ceska gets that freeze spell and unlocked the other entrance. Now what? Apparently I'm supposed to find a new Warp Zone on another island in order to get into the ruins, but I can't find it! Sorry if this is the wrong place.
