Thieves Guild Universal Code

The Thieves Guild, in its various iterations, has always possessed many secrets, and just as many means of keeping them safe, from hidden lairs and training grounds to secret codes such as the Shadowmarks. The Thieves Guild "Universal Code", far more recent and complex than the ageing Shadowmarks, is one such method.

This code was created as a means to pass hidden messages after observing the Dragon Alphabet located on word walls all throughout Skyrim. It is written in an up-to-down fashion to further confuse any would-be codebreaker and uses dots, dashes and lines to create its alphabet and numbering systems.

Letters
Though it shares many physical aspects with the written form of the Dragon's Language the alphabet is entirely different, replacing a letter of the common tongue with a sigil inscribed to appear similar to Dragon Tongue.

Numbers
Unlike letters, the numbering system of the Universal code uses simple, single symbols, again stylised like the Dragon Language.
