Gemanimanati

From the Latin roots "geminae animarum," literally "twin souls," and "nati," meaning "born." This origin is for plurals who have been plural throughout their lifetimes with one other soul, or "twin soul," reincarnating into one body over and over again. The souls may take turns being hosts, it may be random, or one soul is the host throughout every incarnation. This is a soulbased term and a subset of protogenic.
