Fable of the violet haired Princess
The yellow monks are the main worshippers of the yellow cult, a famous religion spread in the Blossom Kingdom. They tend to be independent and have their own rule codes, but are welcome in the Kingdom since they pay taxes on a regular basis.
Yellow monks raise trained birds for fast messaging between distant monasteries and temples. Sparrows and ravens are commonly employed for these tasks, but they also use other bird species.
