Heavenly Guard, Salfir the Woven Serpent

The ever faithful servant and guardian of a long forgotten lesser moon godess. She was once a normal serpent born without skin or scales, finding its way deep into the underworld the serpent crossed path with the trapped godess who took pity upon it and weaved her own feathers and hair into a hide. The serpent remained by her side and perhaps due to the influence of the underworld in which they resided or the goddess presence, the serpent grew and grew. It's mind widened and its body came to resemble that of the godess herself. It did not take long before the serpent, now dubbed Salfir proclaimed herself the guard and knight of the godess, to whose side she remained to this day when you, dear adventurer, reached the hidden room and once more set the wheels of fate into motion.
