From the English language Introduction:
Valley of Eternity is a roleplaying game about everyday heroes and fate as an outcast, reserved for those who are in any way different from their fellows. The game is about penguins, because penguins are funny. A touch of comedy makes it possible to relate to even the greatest of heroes.
You can play two kinds of characters in the game. Penguins represent civilization and society. They live on the Silent Coast and their heroes are sworn to protect their fellows from the dangers that lurk out in the sea, sky or glacier. Anti-penguins, on the other hand, are barbarians that pillage penguin communities and live far out on the glacier in small tribes.
The penguin characters are heroes. A hero is someone who has made significant personal sacrifices in order to ensure the well-being of others. The penguins played in the game have rejected their chance of building a family and taking part in the everyday lives of the regular penguins around them.
A hero is far from a typical penguin, since she’s ready to rebel against tradition and choose her own destiny. She realizes that in order for the community to have a bright future, someone must grab a spear and go on to perform deeds that are simply unimaginable for normal penguins.
