Another Usean unknown country... I think Amber may be the place where Hatties Desert (and Stonehenge) is located, Amber may be the country we see in the map right west of Erusea and South of San Salvacion. It might be correct, because it is said that the FCU and Erusea had tensions over the Amber-Ugellas border. So I think Amber is the one next to Erusea (and Ugellas by the way is the one south of Amber).
