StarClan

StarClan is made up of the dead cats from the four Clans of the Forest. StarClan cats live in their own forest in their afterlife. They leave starry pawprints, and their pelts glow with a pale light, which makes them look like they have stars in their fur. StarClan is sometimes referred to as the "fifth Clan" of the forest. They watch over the Clans from the sky and sent prophesies to warn of impending danger. At every half-moon the medicine cats of each Clan go to their "sacred place" (Moonstone or Moonpool) to speak with StarClan and receive advice about the future. When a new leader is appointed, StarClan gives them their nine lives and replaces the latter half of their name with "star".

Information

 * StarClan sends messages to the Clans in times of great danger or confusion. Medicine cats receive these signs at Moonpool or Moonstone. To receive the signs of StarClan medicine cats either drink the water at Moonpool or touch noses with Moonstone. StarClan can also walk in cats dreams to give them signs even though they are not at Moonpool or Moonstone. StarClan has no defined leader or deputy, but when a leader dies, he or she keeps the -star suffix in their name. There is also a Place of No Stars, which is the opposite of StarClan, where cats who have "caused great pain in their lives" go when dead. StarClan cats can enter the Place of No Stars, but they run the risk of being trapped there, unable to exit the Dark Forest.

Silverpelt

 * Silverpelt is, in essence, StarClan's territory. In the fandom, Silverpelt, which is a large, cloudy-looking swath of stars, is believed to be the Milky Way. Clan cats believe that, upon dying and joining StarClan, a new star appears for the deceased.

Whitestorm and Bluestar then come and join them, and they begin arguing about the three kits in the prophecy. Later, when Jaypaw travels to the Moonpool, he walks in Littlecloud's dream, where Runningnose is talking to him about restoring Blackstar's faith in moving to the lake. Sol also deludes Blackstar and convinces him StarClan is not always right. After the Gathering, Jaypaw is visited by StarClan in a dream, where Yellowfang reassures him that all answers will come in time.

Trivia

 * It has been said by the Erins that in StarClan, any handicapped cats would have their senses restored (like Snowkit being able to hear, Longtail being able to see again).
