Freyalian magic

Freyalian magic is the name given to the crystals and water believed to harness the powers of the goddess Freya. These crystals can summon magical ghost creatures if the water from the Crystal Lake (also contained in the Lovely Fountain) is poured on them. Any crystal is capable of doing this but the magic is specifically used by Freyists for Freyaline and Lovemian crystals. Freyism incorporates many crystal-themed things in the religion, such as familiars summoned by crystals, praying ceremonies using crystals, and the Freya Church uses many crystal imageries.

Crystal ghost pets can transform to resemble any type of animal, these pets are often used like familiars and can also be taught commands/tricks like a dog - for example, Mira's axolotl ghost pet Weed knows how to drive and do specific chores for her.
