Obviously we don't have further information, but the fact that there are Hrothgar (and supposedly Viera due to Erenville coming along after mentioning a homecoming in 6.4) is neat.

The New World seems to be split in two parts, with the north remaining hidden. I wonder if it will be further explored in this expansion or if we're staying in the south.

It's also interesting that the Giants were brought up again, they also ruled Abalathia's Spine in the past as well. I wonder if there's a sort of connection.
