Macros the Black is an ancient magician.
He found the dragon Rhuagh with his servant in order to learn the dragon's magic so that it could not be lost. Afraid that he came for his riches, Rhuagh battled for days but was unable to defeat him; Rhuagh then taught him as much as he could for three years and became his first human friend.
Macros also taught Rhuagh about healing the wounds of the heart and mind, and how to respect all life. Before leaving, Macros left a last gift for him, a magic rod to be used upon the dragon's death, so that no bones should be left for the scavengers.
