Will be continued during the following worlds, and we know some of the names from in-game speech. *Polaris *Emperea *Mirage Now let's discuss what we know about each, as our knowledge is very limited. Polaris: We know it's an ice themed world, given the name and from what we've seen from various random Pirate101 images depicting Penguin and Polar Bear residents, unseen apart from Polaris most likely. Emperea: Even less, but I do recall an NPC in Wysteria mentioning "the rainbows (or skies, it might've been skies) of Emperea" and how they loved them. This suggests the world will be themed around an aerial-type area, probably featuring Pegasi or other sky-bound animals. Mirage: Going off of the theory that the Sultan's gear and house are early teasers for Mirage, we can assume it features similarities to Krokotopia, but instead of utilizing an Egyptian theme it uses an Arabian theme. We also met a resident of this world (once again in Wysteria) who wore something very similar to Arabian dress. Though the info here is very limited, the point isn't to expose what the worlds are about. It's to incite conversation. Anyone has any thoughts on the matter, feel free to leave them down below. ~Oran Sunleaf,
If polaris is an ice themed world, would it be possible that Nodor (a land of woolly mammoths) mentioned in an avalon quest is an area in Polaris? As we've seen in Wysteria how Beatrice Wildwind was from Wierwood, but instead of a world It turned out to be a place in avalon (another name for the wild wyrd and I guess dun dara). Is this same concept being used to foreshadow an area in polaris?
