Probably nothing but for what it is worth…
Scytl is only a couple of letters away from Scytale which is the name of an assassin from Frank Herbert's Dune series. Also it is the name for an ancient cryptographic tool used by the Greeks.

In the Dune series Scytale is sent by the old guard/powers that be (aka DS) but only succeeds in blinding Paul, which paradoxically makes Paul more dangerous. Paul's son Leto II is also known as the God Emperor of Dune.
Scytale
In cryptography, a scytale (/ˈskɪtəliː/; also transliterated skytale, Ancient Greek: σκυτάλη skutálē "baton, cylinder", also σκύταλον skútalon) is a tool used to perform a transposition cipher, consisting of a cylinder with a strip of parchment wound around it on which is written a message. The ancient Greeks, and the Spartans in particular, are said to have used this cipher to communicate during military campaigns.
The recipient uses a rod of the same diameter on which the parchment is wrapped to read the message. It has the advantage of being fast and not prone to mistakes—a necessary property when on the battlefield. It can, however, be easily broken. Since the strip of parchment hints strongly at the method, the ciphertext would have to be transferred to something less suggestive, somewhat reducing the advantage noted.
