Here is the second legendary trio of Urora.
They are three spirits, representing states of matter/classical elements, and carry an orb of said element with them.
solid/earth - liquid/water - gas/wind
of course they fittingly resemble a land-dwelling 4 limbed creature, an aquatic creature and a bird-like creature.
#166(824) -- Solider - Ghost / Rock
#167(825) -- Fluiquid - Ghost / Water
#168(826) -- Aerogaos - Ghost / Flying
There will be a fourth superior legendary representing plasma/fire later.
Guess what kind of creature that one will resemble :P
