Sphinx

Sphinxes are known for their cunning and vast intellect, and many never speak save in riddles. They are aligned primarily with blue magic, though some may be white and/or black.

Sphinxes have hollow bones that can function as organ pipes, so “every phrase is a motif and a speech can be a symphony”.

Some sphinxes have excellent hearing and apparently can tell truth from lies and separate truth from honesty.
