Beta's form of greeting, commonly used in closing in letters, is written as ___kai___ (spoken as "Phi kai Phi"), kai merely being the greek word for "and" and Phi being the first initial of two words. It also serves as their secret password, the two blanks being words that are never to be written down or spoken to nonmembers.
