The trailer was awesome! I really appreciate everything you guys are doing, Rare! I am really excited for Thursday!
Potential spoilers and speculation below:
I was playing the other day when I encountered a ghost ship fleet around Plunder Valley. I assumed someone had started a quest from the Order of Souls, however, no one showed up. I destroyed the entire fleet without seeing a single player ship. I also noticed that Larinna is telling us that Belle needs us urgently ahead of the next adventure. (I assume this is a bug in the game that's not suppose to be there yet). This is speculation, but maybe Rare is bringing back the ghost ship fleet without Flameheart's head in the sky because we fail to stop the resurrection? Like I said, I thought the ghost ship fleet I fought was an Order of Souls quest at the time, but now I think it's plausible it may have been something that was not suppose to be in the game yet. I guess we'll see.
In the mean time, referring to the trailer itself, "Jim, put the chalice down." :)
