Fire territory is part desert. It is usually very hot, even at night, and there are lava flows and fire bushes. All fire sprites are immune to being burnt in any way, be it fire, lava, or sun. They can also control fire and start it in their hands. The camp is a little crater in the ground with a lava well in the middle and is guarded by a lava moat. Earth/Plant territory has clearings but is mostly an overgrown forest. The camp is in a clearing with a tall tree in the center and is guarded by said overgrown forest. Plant sprites can make plants grow a bit faster, but not control them. It's also a bit slow, so, for example, it takes a few minutes to make a seed grow into a flower, and an hour to make an acorn grow into a full oak tree. Water territory has many lakes, ponds and rivers. The camp is located in a cave behind a large waterfall, which guards it. All water sprites are fast swimmers and cannot drown. They can also control water and summon it in their palms. Ice territory is a winter wonderland, with frozen lakes and ponds. However, in some places, it is an unforgiving tundra. The camp is located in an ice cave guarded by said tundra. All ice sprites are immune to the cold and can freeze stuff. This doesn't mean they don't get chilly, though, and still wear winter coats. Lightning territory is a bit elevated. The ground is rather rocky, and very rich in iron, making lightning strikes very frequent. The camp is on a hillside without too much defense except for the winds and lightning. Lightning sprites can control electricity and are immune to it. Air territory is very hilly. The camp is located on a mountaintop at cloud level. It is guarded by strong winds and the sheer cliffs. Air sprites can 'fly' a few feet off the ground for short distances and not get blown off track. They can also control movement of air.
The forbidden forest is basically the outlands. It is a forest that is matching Earth territory in thickness. Sunlight has a hard time getting through the trees, so it is always dark under the canopy. In it live creatures such as timber wolves literally made out of wood. Other creatures are more like sentient plants; giant venus flytraps and plants that look like harmless buds waiting to bloom but are actually full of teeth. It is against the rules to enter the forest, but you shouldn't need rules to not want to go. The heart tree is the tree in the center of the territories. It serves as a meeting place, and has a magic crystal inside of it that powers a forcefield to keep out the forbidden forest and gives sprites their powers. This crystal draws power from positive energy, like getting along. Fighting among the elements will unbalance it and weaken it's power.
