Children of the Divine Order
The legacy is an order within the wider group of the kin. Children of many different gods/goddesses participate in different ways. Their mission is to save the knowledge of the kin and the kin themselves.
One part of the organization tries to collect the lore passed down from various groups of the kin. Sometimes this is simply talking with elders and lore keepers. Other times this is either bankrolling or doing archaeological research themselves. The hunters have gone to great lengths to destroy the heritage of the kin and the Legacy directly tries to rebuild this.
The other part of the Legacy seeks out other children of the gods/goddesses who may have been lost due to accident, ignorance, or the efforts of the hunters. They track down unexplained events and police cases and see if their is a supernatural link.
