In order for a search to be made to locate birth relatives of the adopted person, the Intermediary Agency (IA) applies to the General Registrar's Office (GRO) to
obtain certain pieces of information to enable them to begin the search for the birth family member.
Afterwards, you may dig further by collecting and examining drops from
certain monsters, which will tell you the
information you'll need to
obtain the exact
piece of material on your wishlist.
