Trying to track down my long-lost sister, I've been instructed to look for the native village where she's held, near Corpus Christi. So I'm looking and haven't found anything. Can anybody help?

If its the mission I'm thinking of, like others of its kind, your ship has to actually stop on the "tile". I forget which side of CC it is, but starting at CC, move the ship one tiny step, let the interface report him as idle, them move one more tiny step, all the time hugging the coastline. Its been a while, but I don't recall that one being tricky, just tedious.

Be sure to check in the little bays. IIRC, there's one just north of CC, and one a little further south.

I've never figured out just how close you need to be, but if you aren't right on the coast, you won't get credit for it.

That worked, and I should have fathomed it on my own. Years after I was given the mission, I could still do it.

I think I got 200,000+ gold for doing the pirate I came up against and I got a letter from my sister.
