Description

Humiliated by your first victory, Sauron strengthened his security measures. Finding the idea of parting with his ring-based encryption repulsive, he arranged with his underlings to change the ring after each encryption. Fully confident in his new creation, he exchanges crucial messages with his most loyal servants.

The elves have managed to intercept a mysterious document, this time encrypted with a unique ring. Will you once again show Sauron that even the most powerful of Dark Lords can be defeated?
