This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Tianlong (Chinese)
Tianlong, literally meaning "heavenly dragon", is a divine flying dragon in Chinese mythology as well as being regarded as a star in Chinese astrology. True to the meaning of its name, Tianlong is a divine dragon that spends its entire life within the heavens. Its purpose is to guard the palaces of the gods as well as their treasures.
Tianlong is also known to pull chariots that the gods ride within, with him also acting as the steed for the Chinese deities in order for him to transport them into any location they desire. No matter the distance, Tianlong is able to reach it and never tires from his journey.
