It's Trapped

Dragon Valley, Soul Realm.

Link told his plan to Lucia, who shook her head. "No, I can't do it. I don't have enough power right now. Even at full strength, I don't think I could restrain it. Also, my runes only work in the material realm. It's useless here, but I can't go back to the material realm."

Any normal human would have been desperate at this point. Even an ordinary Magician, upon hearing this, would have thought, 'That's it, it's hopeless.' But Link's first response to this was to think, 'There has to be something we can still do.'

After a few seconds of silence, he spoke. "Miss Silverstar, do you mind sharing the details of your Rune of Principle with me? We'll take it from here. This is Dragon Valley, after all. With the thousands of Red Dragon warriors here, power is something we have in abundance right now."
