Well it took you six hours to get here and you have been here a day.
Combat weapons are listed in the rules; so long as you have Combat you can always bring one. But remember, only armed Combat schticks work with them.
Gondekorro is not a good place to load up on technical supplies and the like. You could buy essentials here but they are not what you are short of (though since the raid on Newhaven your problems are eased for now- the trouble is that these raids turn into a security nightmare for you, with the Bureau on your tail again).
In fact, you do have a contact who can get you... almost anything if you have the money, and he/it works anonymously too. Trouble is you have no idea where the Flotsam is and how to get it to come out to Epireus.
In all important game ways, there isn't anyone else of importsance on Gondekorro- Zorin is Mayor, Sheriff, Magistrate, Governor and so forth. There are docotrs (and undertakers...) and the like but there's no real need for any detail with them.
Is Dak going to eat his money?
