Faeloria's pocket dimension was something of an enigma, an extension of her very essence and connection to the World Tree.
She could open entry and exit points virtually anywhere, as long as two conditions were met. First, she had to have visited the place before. Second, it had to be within reach of the World Tree's sprawling roots or its towering branches. These boundaries were not as limiting as they seemed, for the World Tree's influence extended far and wide, crossing entire dimensions and touching many sacred places.
In other words, it wasn't difficult for her to open a path back to Orinfeld City.
