A daughter of the Falathrim, Aearlinn stands at 5' 7", and is of a petite build. She has long, dark blonde hair and bright almond shaped blue-grey eyes. Her expression is usually a tranquil one, though she can be very stubborn at times. Aearlinn is a little shy until she knows folk, but she is naturally caring towards others. 

She works mostly with her hands, sail making by trade but she has also been studying Lore at Mithlond, and with the Nolde Danel. She loves animals, and can often be found with bird companions, and sometimes an old lumbering she-bear. Her clothes are plain and often home made. Mostly woolen and linen dresses that allow her to climb over the shores to the sea, and run through the woodlands with her animals.

She speaks Falathrin, Sindarn and has a little Quenya of late. 

Her most outstanding feature is her eyes. They are hauntingly reminiscent of the moods and depths of the sea.
