So, the work mentioned here has been discussed publicly a few times in game but I'm adding it here so everyone can see.
For the longest time people have been asking "Why isn't there a pterosaur we can use to fast travel to the bronze door fortress?" Originally I think it was felt the area was a "High level" area so you shouldn't fast travel there, though I'm not really sure what the reason was.
This view is no longer the case and we have added a pterosaur in the fortress, the idea here is increased playability. Using this fast travel will be a little different to other pterosaurs as access is by quest only. That quest will originate in the fortress, and once you complete it you be rewarded by being allowed to travel to and from the fortress by pterosaur.
It was also brought to my attention that the travel time for the pterosaur was too long, so we have looked at that and reduced the time taken for many of the travel routes. This is again in an attempt to improve playability, by reducing the amount of time you literally can't do anything.
We have also added options to allow travel from any city to any city. The Hydlaa<->Amdeneir path is still the only free one as it's the only way to get there. So once you have completed the new quest you will also be able to travel to and from any city and the fortress.
This work is all completed and is set to be fully released in the next update.
Enjoy.
