I am of the Sidhe..
There will always be a strong link between the Sidhe and the Annunaki progenitors.
From my feelings, experience, and upg, Sidhe are akin to the nephilim, rephaim, and often vampires. These names are due to contact with various peoples, since our family scattered into clans across the realms.
I don't remember too much as it is, only somethings in dreams, though there is a strong resonace with the Gods of celtic culture, biblical Rephaim & Nephilim , norse Jotunn Vanir & Elves , and Danavas of the Vedas, all in a very compelling way..
I know i am of the Sidhe because, i feel it in my blood, spirit, mind, and soul. A calling if you will.
I enjoy study of genealogy, and as welsh royalty, i am descendant of Beli Mawr.
Being of old scots lineage, i am descendant of Tuathe De Dannann or Fomorian..Perhaps both
I am also of merovingian blood, though i know very little about this line.
Besides descending from shamanic igbo high cheiftians, my lineage consists of danish, a groom from fyn, and prussian peasants. There are many who would say my line is diluted by lowborn people, but it dosen't matter much to me..I know i am divine. A god and giant in my own right, what more matters?
De Dannanns were fair to behold as all know.. They litterally shone with light and radiated divinity and supremicy.
Their pressence commanded respect and reverance.
Though such beauty could turn into horror(and often did), just like the seas.
Psychic abilities, Red hair and green eyes, and tall stature are the main leagacy and immeadiate signs of descendancy from these lofty lords and ladies.
In my opinion there are black elves, and they often look like glorified negros and berbers.. The Olmecs, Wakyambi, west african, and carribean Gods etc, in my opinion, are examples of what one might call black elves, and possibly fomorians, though this is debatable..
Also, i suspect there are other ''Elfin'' races, like the mermaids, that exist in places sapiens don't imagin possible.
In a nut shell, Elves were sacred Giants; banded together with other Giants, to protect and better the race. In yore, They were the kings of men and heroes of epics. They were great and mighty shamans highly skilled in mathematics, arts, astronomy & astrology, alchemy, hypnosis, metallurgy, wortlore, warfare, masonry , and all kinds of engineering and science. In the minds of men, They could be the one of the most beautiful charming and alluring peoples, and also one of the most terrifying unimaginable monsters from the depths of an abyss.
