I've got another bitsy of lore, that you might like:

Pathfinders.

They are young pure spectral fey-spirits.
They feed on dreams and are small but curious creatures. Generally good natured and with a little bit of a mischievous attitude. Most of the time the watch over children and feed off their dreams as a sort of spirit guardian. 
They tend to use portals to zip in and out of the world and are usually small.
As said usually act as an inner voice/instinct or a spiritual guardian for infants and small children and usually leave the child when it grows up or stops interacting with it.
Or unless the child becomes more antagonistic towards it. Despite their magic they are rather skittish and require a gentle touch. It is why they don’t do well in captivity.
They in the end they usually act as familiars for the magic casters or return to the world of dreams and shadow. By this time they have perfected and solidified their own form and intent, representing usually an intent similar or opposite of that of the magic wielder in order to complement them.
Keep in mind they choose the one they bond with, not the other way around. 
Those that get a Pathfinder have a great responsibility as corrupted ones can turn into some of the most deadly and dangerous Fey creatures imaginable.

Some examples of what they tend to look like:
