Keys

"What are we going to do?" Erza asked.

The explosion alerted her. She didn't expect the others to find the passageway to the Great Tree so quickly. She was afraid they wouldn't get into too much trouble because of it.

"Nothing. At least for now." Wain muttered, "They're probably going through one of the Seven Trials, so we'll meet up with them later and get the key or meet right at the gate to the Great Tree. Either way, we'll have to fight."

The others nodded. They continued on their way. Because of the size of the root, they thought it was close, but in fact, the root was more than ten kilometers away. Occasionally the Spirits would fly up to them, but at those moments, they would speed up and not let themselves be held up by small trials.

"Great. We're here." Ern said as he looked around.

They tried to find a symbol or sign for the next challenge, but only roots and foliage were around.

"Hey, isn't that where...?" Wain muttered.
