I was looking at the Pirate101 website and I noticed that the leader of Polaris was Napoleguin. Most people think that Polaris is an ice world, which it probably is (hence napoleguin), but Napoean was the emperor of the french empire in the 1800s so Polaris could have a french theme, and this would go nicely with the other european based factions in pirate101. So if we do end up seeing Polaris in Wizard101, I think it is possible that it could have a french theme, meaning that it would not be friendly with Marleybone and that we might see some signs of a revolution that mirrors the one in the late 1700s in france.
