Macsethian

Macsethian is an universal language that was spoken and understood by all or most of the Tower's population. In short, Macsethian is the primary language within the Tower.

About
Macsethian was named after The Great Father Macseth, a famous inventor and weaponscrafter.

There are many different languages in the Tower. In order to solve the communication problems resulted from the language barrier, Macseth invented or created a device called a Pocket. One of the function of this device is to translate those different languages into Macsethian because it was used as the standard language setting of the Pocket.
