Theta Delta is the unofficial Therian
logo. As there is no central or ranking authority and most therians are very independent, this logo is a common and, for the most part, accepted and liked, but does it does not carry an official status. Individuals may reserve the right to use or not use any derivation of this symbol without anything being assumed of the individual, except that the individual doesn't particularly like the symbol.
It is made of the two greek letters:
- Theta: similar to Theri; represents the human component
- Delta: Difference; represents the animal component
