In ages past, the Star Charters Guild was created by the Noor of Alhambra and her Royal Astrologer to study the sky and all its mysteries and wisdom. It creates Charts of not only the Alhambran Sky but also those shadows visited by its members, and even Amber, which are made freely available, in most cases, to any member in good standing. The Star Charters Guild is used to train worthy Alhambrans in the arts of Starwalking and are said to possess other magics not common in Alhambra.
Each Embassy in Shadow has a representative of the Star Charter's Guild assigned to it, there to study the night and day skies of the place and provide relevant aid to the embassy staff. Many are also skilled in the arts of divination.
