The Thieves' Ogham alphabet was invented by River Langham and two childhood friends. They used it in an imaginary game set in medieval Scotland. Within the game, the backstory was that it was used to write "Thieves' Galk", a secret language used by a secret society of bandits and pirates, made by combining Welsh, Irish, and Scottish Gaelic. In real life, the inventors mainly used it to write secret messages in English.
All human beings are born free and equal in dignity and rights. They are
