The places you can go is:
-Lonely Cave
-Ascension island (It's above the cave in Lonely cave XD)
-Sky's Rim (You have to climb to the top of Ascension island to get to the portal, whicha heap of fun XD)
-South pole (A pretty bland map...)
-Atlantis (Hidden somewhere in South pole, hard to find. Somewhere at teh upper left hand corner of teh minimap.)
-Last Cave (I haven't been there because the portal to it doesn't show up in my game for some reason >.<)
-Bonfire (Where the trolls and rule breakers used to gather, a trouble spot.)
-Ficho Caves (Takes you from Bonfire to Flourite plains)
- Flourite Plains (Biggest map I think? But pretty empty of features)
- Cape of Distant worlds (This is where the portals to custom downloaded maps will show, there is a portal in teh water in Lonely Cave and one on a Island in Flourite Plains.)
- Temple of dreams (can be found in Flourite plains)
I think there may be one other that I have forgotten...
And the whisper is a function in game, basically a private message. There is a bubble above the section of the chat where you type that says Local. if you click that you can choose which chat type you use. Local only sends your message to those nearby, general sends the message to everyone on the map, Group is for if you have joined a group, people in teh group will use that, Party is if you just have a bunch of friends and you want to chat together, whisper is as I said, a private kind of message. You have to type the username in the box that will appear next to teh button to send a whisper to that specific user.
