[Lotr The Two towers] Why is the Forbidden Pool forbidden?

Henneth Annûn is a sacred place to the rangers of Ithilien. The location of the refuge is a closely guarded secret, because it provides protection from the dark forces of Mordor. That is why the punishment for entering it is so harsh.

Entering the refuge without permission by the rangers is punishable by death. Even if an outsider accidentally discovers the location he would still be subject to that punishment.
