Fourtrees (known by the Twolegs as Druid's Hollow) is a group of four tall oak trees located in a hollow, that the Clan cats have held their Gatherings at since the early days of the Clans. Fourtrees is described as neutral territory, and is often used when cats from different Clans want to meet outside a Gathering. In the middle, there is a steep-sided clearing and in the center is a large rock called the Great Rock, which is noted to have jagged edges. The Clan leaders use it to look down on the Clans and share their news during Gatherings. They are also referred to as the Great Oaks.
The Moonstone is a giant quartz crystal which has never known the warmth of the sun. This is where leaders and medicine cats go to share tongues with StarClan. Leaders go there to receive their nine lives or ask StarClan for help. Cats lie down with their noses touching the stone then get visited by their warrior ancestors.
When a Clan cat dies, they will be guided to StarClan by a deceased cat who played an important part in their life, such as a mentor or a cherished family member. When a cat dies and goes to join StarClan, they merely close their eyes and reopen them. StarClan cats leave starry paw prints, their eyes shine like stars, and their pelts glow with a strange light, which makes them look like they have stars in their fur. Frost sparkles at their paws and glitters in their eyes. Their pelts shine like ice and carry all the scents of the seasons: the tang of leaf-bare, the green scent of newleaf, the musk of leaf-fall, and the sweet blossom of greenleaf. The cats' spirits remain in StarClan until they are forgotten by all living and dead cats over a long time and earned their own peace, causing them to fade away to little more than ghost-like images of themselves.
