This and That: Secret and Cypher (Savage Worlds)
Secrets are valuable. Knowing the enemies' orders can win a war. Knowing a competitor's recipe for superior steel can make you rich. As long as there have been people¸ there have been secrets. The trouble is that sometimes you need to share these secrets¸ but only with a certain few.
That is why humans invented ways to hide secret messages¸ an art known as steganography. Of the many ways to hide messages one of the most popular is cryptography¸ the means of turning messages into unreadable blobs of text and then back.
Secret and Cypher includes:
A real world history of cryptography Optional rules for encoding and decoding message New equipment 1 new power 2 magic items 3 new monsters
