If you successfully completed Bird Mask Cantergloak's death-defying leap wingsuit jump lol through the guarded ruined bridges, this would be the arrived area to the mountain ruins of the Old Monastery. Cantergloak could probably be persuaded to permanently join the sky galleon and Lady Scantgrace, and he could help upgrade it with some flying kite sail vehicles. Also you would have effectively unlocked a secret alternative flying trade route through the mountains, that bypasses the Warguild tithes and cannon-towers and circumvents the Maelstrom and lightning storms above. I had some ideas for a cartographer type npc and some ship charting / portolan navigation upgrades but that was not fully planned out yet.
