Owh, no I didn't bother to check. But I've checked my warrior with 100% canthan for you and it isn't explorable, or at least, my warrior has got 100% and hasn't explored the part your showing, it looks excactly the same on my warrior. The little squares can be explorer though.

Follow the Yellow line I've drawn on your map and it should get you the bit on the end. I'm not sure how to get that bit in the middle though.

you can get to 100% without that area.i never did figure out how to clear that area but managed to get to 100% without it.
