Alaihar

While these creatures look like majestic and colorful birds, they are in fact an offshoot of true dragons. Alaihars show their ancestry in their fiery breath weapon, scintillating feathers and great mastery of magic.
An alaihar is capable of casting spells as an eighth level sorcerer, but also treats cleric spells as arcane and can learn spells from that list in addition to wizard/sorcerer spells.

The habit of young alaihars to seek battle against evil leads many of these proud dragons to die young. In contrast the calmer and wiser elders prefer to act as mentors and advisers to young heroes.

According to dragon legends an ancient red dragon who bested his golden rival sought to humiliate his enemy yet further by transforming him into a mere bird. The power of the golden dragon could not be unmade so easily however, and the descendants of the dragon showed much of the powers of true dragons.

The falling gardens of Attylon are famed above all for the countless birds of paradise that make their homes there. But only the priest-emperor himself knows of the Alaihar who are his foremost advisors.

An evil abjurer seeks the last ingredient he needs to close a city of from the gods themselves. The living heart of an 800 years old Alaihar.
