Aslan's Country

Aslan's country is to the far east of Narnia, Archenland, Calormen and Telmar, boardering the Silver Sea and is ruled by the Emperor-Over-The-Sea and his son, Aslan. The land has great mountains and is modeled after Heaven, being the place where the deserving dead from the World of Narnia linger for eternity in euphoria and bliss. It can be entered from any world not just Narnia.

Humans
All of the humans who ruled over Narnia entered Aslan's Country. Peter Pevensie, Edmund Pevensie, and Lucy Pevensie three monarchs from the Golden Age of Narnia entered Aslan's country after they were killed in their own world by a train accident.

Their parents who were killed in the same accedent also entered Aslan's country but not through the door from Narnia as they had.

Jill Pole and Eustace Scrubb were killed in the train accedent in their own world but went through the stable at the end of the world in Narnia

Narnians
All good Narnians entrd Aslan's country before the end of Narnia during the Later Ages. They entered when they were thrown in to the stable at the Battle of Stable Hill. King Tirian was the first to head through the door.

Another Narnian of note was Reepicheep, who set out to sail to the end of the world after The Voyage of the Dawn Treader and entered Aslan's country when he reached the end of the world.

Evil Beings
Servants of Tash and Narnians who have turned against Aslanare returned to Tash and are not allowed to enter Aslan's country. The are also struck dumb and loose the gift of speach they were given at the creation of Narnia.

Susan Pevensie
When Jill and Eustace enter Narnia for the last time Susan is no longer a friend of Narnia. Therefore she is not present at the end of Narnia like her siblings. This does not mean however that she has never entered Aslan's country since there are ways to do other than from Narnia.
