Seebling babies do not have unity symbols on their palms, but as they grow to adulthood symbols emerge. The colour of the symbol determines the tribe from which their life partner will come and the shape of the symbol will be identical to that of their future partner. When they discover a Seebling with an identical symbol, they will eventually unite.
