Dzree was the loyal student of Sh'kial, the first Dragon Priest. While Sh'kial was fanatical, Dzree had a darker idea of what should be offered to the World Dragon. Once Sh'kial found out about Dzree's desire to sacrifice Humans and Elves, he spoke out against her. In retaliation, Dzree assassinated him in 205 BL.
Dzree began to lead a new sect of Dragon Priests and as Leader of the Dragon Priests, she named herself High Priestess, and presided over a wide-ranging purge.
"Dzree's sect of Dragon Priests had built up a strong militant power, which they put to use, conquering much of the Five Realms" (Book:RpiRE). Dzree soon became known by a few other names such as The Hag and The Nameless One because many S'Kra Mur felt that she did not deserve a name or had a fear of calling out her true name.
Dzree developed a particular hatred for Bards and during the reign of the Empire "the Bard Guild of that time was completely destroyed" (Book:RpiRE). Many of the surviving S'Kra Mur Bards and Clerics at the time fled to Aesry Surlaenis'a and eventually formed into Ru'atin Peri'el or Sisters Peri'el. The Ru'atin Peri'el dedicated themselves to helping Peri'el keep the World Dragon slumbering. They created a stronghold on the island and for many years never left the safety of its gates.
Sithsia prophesied Dzree's death and after some time she fell, but not from the hand of another. Dzree drove herself insane with paranoia and died alone.
