He can be found on a sidepath just before the entrance to the city, so players will not need to start the Watchtower quest before talking to him. He will accept noted pouches. Players with access to Prifddinas may prefer to use Lord Amlodd who will exchange pouches on the same terms as Bogrog. Having completed the Hard Tirannwn tasks will make Lord Amlodd swap pouches for roughly 10% more shards.
