He starts with Petra, while checking some limits!

"...hmm," he considered, looking between each door.

"Having a tough time deciding, Master?" Sothis asked knowingly. "I get it, all three of them are beautiful girls, it's a tough pick~!"

"Actually, I think Petra might greatly appreciate a dream of her own homeland becoming more lucid," Byleth noted. "I think I'll start with her for now."

Sothis nodded and grinned as she gestured. "Then, what are you waiting for, Master? Go ahead and go into her dream!" she enthused.

Byleth couldn't help but let out a small smile at her enthusiasm, before he asked, "Actually, I had a question... Given that these are lucid dreams, helped along by magic, how much control over the reality in them would we have?"

Sothis paused, and considered. "Probably a good deal," she mused. "Why?"

"So, is it possible for Petra to hear what I say in her language, while she can speak her own, but we hear the Fodlan tongue? Essentially turning this place into an area where we don't have to concern ourselves with the language barrier?" he questioned.

Sothis raised a finger to answer, but stopped. "... honestly? I have no idea. Worth a try though..." she noted.

Byleth nodded and walked through the door. He emerged in a clearing that contained tropical vegetation surrounding it, and had several tents made of animal hides. The mostly nomadic culture was plain to see. There was even an elaborate totem in the center. "Professor?" he heard, and turned to see a surprised looking Petra.

"Hello Petra," he greeted her with a smile, focusing on trying to make her hear his words in her language.

She blinked, surprised. "You have been learning our word for greetings?" she asked him curiously, apparently thinking he had only learned one word."Also, why are we being in Brigid?"

"Well, the thing is, we're not actually here," Sothis replied. "Think about it, how did you yourself actually get here?"

"Erm... Last thing I am remembering is falling to sleep back at... The Officer's Academy..." she realized slowly. Before she could start asking a lot of questions, Byleth began explaining.
