Stormild

One of the twelve Primordials, Unlike others, She is an Elemental which gained Sapience, She may act childish and immature but it is a disguise,

She likes all Elementals and Spirits, And since Sylphie is part spirit, she took a liking towards her and gave a Divine Blessing,

The way she gave Divine Blessings to Sylphie was quite abnormal, It was due to Sylphie's ignorance as she rejected Stormild's other blessings one after the other and stormild had to give Divine Blessing in the end.

She facilitated the Oath of Union ritual between Jake and Sylphie, but due to Jake's bloodline, he unintentionally broke the rules which requires oversight of Higher Being consequently the Oath will only last for few decades.
