The Eastern dragons are the progeny of the Mother of all Serpents and the Lord of the Tower of Heroes. They all have some link to death and to life.
The Eastern Dragons are:
The most political of the Eastern dragons. Matahadraes is associated with renewal and rebirth.
Embodying the state of death. On good terms with the Crimson queen and last seen with Kit Fisable in the very far east.
Associated with decay.
Associated with the moment between life and death. Mother of Enshinevrostra.
There is a fifth as yet unknown Eastern dragon. Some indication that it may be female but even this is uncertain.
