The language of the Grimkin is a complicated system of verbal and non verbal communication, while it takes its roots from the same language as Common, the modern form has diverged so far it is scholastically considered its own language family. Full conversations can be had between experienced linguists in the formal sign language developed within Grim-tongue, colloquially known as Grim-hand. The language is difficult to learn for outsiders, almost by design, and is commonly used by Grimkin to talk with each other while in the company of foreigners.
