???, Balderra
After some time walking along the dusty road, Anik would come across a small village. The land surrounding it would sound, and smell, very much like farmland and most of the traffic passing her by was in the form of carts carrying food around.

Yauna would spend the next eight hours resting, partially thinking about what she could do since she had no real way of getting Anik back any time soon. She considered treachery as the most expedient way to achieve one of her goals, but admitted that this would harm her other goals to some extent.
After the eight hours, Yauna would become ethereal again, and begin moving through the walls of the castle, searching for the room where the mages keeping the portal open were.

The exhibit on the portals would explain that, after years of advancing technology from interdimensionals, the people of Avinah decided to try and locate these other worlds. The study was, for the most part, based on sorcery and rituals to deities believed to have some influence in this domain.
The portal technology, at first, was simply a sorcerer with an affinity for this type of magic. This sorcerer was able to detect minor disturbances and openings in the universe, and widen them to pass through. Once this was used to establish contact with Earth, the two worlds pooled their knowledge together to automate the system.
Dala would also learn that these portals and natural openings created more serious disturbances, and so part of the function of portal-sorcerers and portal stations was to close these anomalies down to create stability. On Avinah, sorcerers typically did this due to their mobility.
The current portal technology was, essentially, a mechanically activated sorcery used to create, widen and close portals between universes which, with enough preparation, could be directed to specific worlds and even specific locations. The Vesh'Rah had been important in the development of this, due to the need for their sky-metal inscribing.
This information would be accompanied by paintings, and photographs, representing the key events in the history of interdimensional travel.
