Heheheh, so here I was, trying CVRL for the first time, and had had my first couple of characters die stupidly. Then, I'm exploring town, gaining a few levels and all, and finally find out that there's no castle around. So I go explore some more. I reach a new area called "castle gates" (if I'm not mistaken), wohooo!
And there's water, and there's a quay type thing leading away into the east. And in one particular square, surrounded by grass exept for one quay tile, something lower, blue... "Hmmm, what is that?", thinks my character. "Let's find out!" He rushes towards it.
It turns out it was just a water square. And no way to get out. Doh! I'm off to try it again!
