Sja-anat's Spy

Sja-anat's spy is a spren which - apparently - is unable to go far without a carrier, so it brings an escort (i.e., a larger spren) which reforms itself into a female knight with a Shardblade in her hands.
==Description==
It appears as a shadowy face with red eyes that swims through the water of the Purelake like a fish.
