From The Heretic Knowledge Vault
Sarna is an elven ranger last seen in Saus, disguised as a human male. She left for Isabel, hunting the two errants purportedly headed that way. Though she is an acquaintance of Sarine, it would not be entirely correct to say that they trust one another. She has been around humans too long, according to Sarine; this could be because of her sarcastic attitude, her carelessness in maintaining her disguise, or because she was so easily fooled by a misdirection of Sarine's.
