What book is the City Bred variant of the Half Orc found in?

Looking to buy another plug in for herolab and don't know what book they are found in.

Thanks in advance.

Check out Archives of Nethys.

If you mean city-raised half orcs (bonus to local knowledge checks and proficiency with longswords and whips) then you want the Advanced Race Guide.
