Map of the Castaway Peninsula:

Locations:

DuneClan:

DuneClan Camp: Nestled between a few palm trees is DuneClan camp. Hidden underneath huge sand dunes, the camp hides one of the only freshwater sources in DuneClan, a small freshwater pond as well as a nice bit of shade to escape from the hot sun. Dens are made of ramshackle bits of sticks and palm leaves decorated with seashells.

Sweetspring: A contested area between GroveClan and DuneClan, Sweetspring comes from a small lake in GroveClan's territory and continues out to the sea. It is one of the few prey-rich areas in DuneClan, and is also their only other source of drinking water. GroveClan also doesn't want to give up Sweetspring because the drinking water that comes from the spring is unusually fresh and sweet.

SilverClan:

SilverClan camp: SilverClan camp is found in a small sweet smelling clearing surrounded by large sturdy oak trees. That and the fact that it's deep in SilverClan make it hard to find. SilverClan camp is full of sweet-smelling flowers, and is generally safe from the worst of weather. The dens are made of leaves, sticks and grass, decorated with flowers. This used to be GroveClan's camp, SilverClan moved here after conquering them.

Moonmirror:A fault of obsidian on a hill on the border of GroveClan and EyrieClan. Medicine cats come here for halfmoon gatherings, and believe they can see visions of Starclan in the mirror's black surface. EyrieClan and GroveClan both wish to control it, both to prove they are StarClan's favoured clan and because the surrounding area is rich in prey.

Abandoned SilverClan camp: On the western edge of former GroveClan territory, Silverclan has made their home. The camp is in and on a high bluff, surrounded by a meadow of sweet smelling flowers. The ground of the bluff is solid, but easy to dig. SilverClan camp is made of a series of  tunnels  which make up the dens dug into the bluff. The largest and most comfortable dens are near the top, the worst are at the bottom. After SilverClan moved to the old GroveClan camp, foxes took it over.

EyrieClan:

EyrieClan camp: EyrieClan camp is found in a cave on the tallest mountain of the peninsula. It is very hard for any cat to access from outside the clan, and the only easy way to enter that isn't scaling a cliff is a secret path known only to EyrieClan and the Children of the Ember. Each den is a separate tunnel of the massive cave. The hard cave floor is cushioned with feathers and grass to make it more comfortable. The only light comes from a hole in the cave ceiling at the centre of camp.

Painted Rocks: This is where the clans have their gatherings. There are three tall stone pillars where the leaders address the clans. The rock face is decorated with strange painted designs made by the Children of Ember.

The Cave of Prophecy: A cave where the Children of Ember gather every halfmoon to hear the Oracle's wisdom. A sickly green smoke fills the cave, rising from a crack in the ground.

The Passage: A volcano at the centre of the peninsula that the Children of Ember believe connects to their paradise. Cats who disobey The Oracle are pushed inside to join their ancestors below the earth.
