I've searched for headless nick, black cove, etc. and I see other problems people have but not this one so I'm very confused. I killed Pontius Pirate after I found the way there, but when I go to try to get to Headless Nick I can't go through the docks, I can make my way past a lot of the traps but the dock platforms don't connect together at some point and I don't see any kind of buttons/switches/levers or anything there ... but since nobody seems to be having this problem that I can find and no walkthrough seems to reference it, I'm not sure what I'm missing ...
Try using the two teleportation pyramids. You can throw one of them over the doc, and have your character use the other one to teleport.
Then you can "send [the pyramid]" to the party and have them teleport to you.
