The changeling network started as a phone tree more than anything else, watching for amber alerts and escaped changelings and arranging for them to be placed with families who knew about the supernatural and were sympathetic to the plight of changelings. Now it's a full-on organization, working with the Sanctuary to place changelings in safe homes at a much larger scale, re-integrating changelings, seeking information on past identities to allow for reintroduction to birth families where possible, teaching glamour, and attempting to better the position of changelings and their defenses against the true fae. All trustworthy changelings and sympathetic supernaturals are welcome, as are mundanes who are both aware of and sympathetic to changelings.
