I feel that when you buy a teleporter in the crown shop, you should have a second teleporter to teleport back to the other one. I have a teleporter that teleports me to another house, but I can't teleport back. It is so hard to go back and forth as I please. I wish that there was a way without buying another teleporter because crowns are expensive and I need them to unlock new zones. thanks
You don't really need one to teleport back to your first house. Just click the home button. As someone else said, when you get to Polaris they drop like crazy. Gearwise in Celestia sells crafting recipes for them too. They use easily obtained reagents and cards and only require Master Artisan crafting (Dragonspyre crafting quest).
