Methabeht is certainly not a name from the true tongue of the Tinai but it some other race that potentially existed a long time ago. The tales of bards that have been passed down for generations speak of him as The Life Bearer and he is often associated with healing and birth.
However, due to the age of the stories most people do not believe him to exist accept a few prophets often branded as madmen. Including the Cult of Methabeht.
In the tales The Tinai, a race of angel like creatures, were known to worship him and him alone.
