So because I have an unhealthy infatuation with what was once the "raid on the refinery mystery ship" which is also still visible in the new 2v2 map, Blackcliff, I would like to speculate a bit on the ship's in world purpose, faction affiliation, and a fitting name for fun. Older images of the ship can be viewed here

Assuming that the map Blackcliff exists in the same location as the Blackcliff on the GoI Co-op Mode map
(
http://img2.wikia.nocookie.net/__cb20140314035859/gunsoficarusonline/images/2/27/Guns_of_Icarus_Map.jpg ) we can assume that it is a major town in the Fjord Baronies territory near the Chaladon border. In spite of this though I'd like to theory craft that this ship, while seen in Baronies lands is not a part of the Baronies faction or at least not its military. This is because its design does not share some of the very common characteristics we've seen so far in the Baronies' faction ships. From the Faction A.I. ships as well as the previewed faction player ship, to the Spire that has a history as a former Baronies sentry we can see that the Baronies military has a thing for implementing shields or some kind of "cow catcher" to the front of their airships.
The blackcliff ship (blackcraft?) is perhaps instead less of a military ship for the Baronies and more of a privately owned cargo ship for the Blackcliff refinery. Larger balloons meant for bearing heavier loads, a single large howitzer type weapon on the front for self-defense rather then aggressive action, and a simple cost effective design could imply that this airship was designed with freight in mind. Some old name suggestions included the narwhal because of its pointy bits. Maybe a Marlin or Sailfish would also be good suggestions in-keeping with the marine animal naming theme.
To my knowledge the inclusion of this ship in the Raid on the Refinery map was mostly due in part to the convenience of reusing old assets. The first time this ship was seen was in the GoIO trailer which can be viewed here at the 11 second mark.
https://www.youtube.com/watch?v=Ewpn5xMY3Hc The ship was too large and/or didn't function well in the PvP setting of the time so it went unused until it became a fancy background decoration. So having said that this is all of course speculation that probably has no connection with the developers intent and is really just for some fun. Any thoughts?
All credit that needs to be due to the fine folks of the former thread to first identify the mystery ship here
