Have to ask for clarification on nature of Asimar knowledge of Celestial language.
Supernatural, other, Is it "in the blood" somehow?
They say "the language are primarily symbolic in expression, relying on hieroglyphic-like images to communicate their meaning".
For example, if no one spoke to Aasimar in this language since her birth. Does Aasimar think Celestial? Or some kind of initiation is required? Can Aasimar at all be oblivious to who she is? If she suddenly would find hieroglyphic-like images of Celestial writing, would she automatically be able to recognize, read and answer them? If someone would talk to her in Celestial, first time in her life, would she be innately fluent in the communication?
