Once they arrived at the supposed site, Aria crouched and pointed at one spot on the ground.
"This patch seems overflowing with energy now that I pay close attention to it." Aria hummed as she called Rallaka over. "Dig this up, will you?"
"Who do you think you are?! Who do you think I am?!! A great spirit, used as a digging tool for this kind of small task... I... will accept this. I was just kidding, I'll do it." Rallaka was about to protest before she received a sharp glare from Aria, which made him cower back and do the deed.
Rallaka used his Earth powers to rupture the ground and pull apart the foundations. After some layers, a hole was revealed, along with a switch like Alena had mentioned.
It was an incredibly inviting mechanism. Every single part of it screamed 'press me'.
"Ho-oh, so I just have to press this, right?" Aria rubbed her chin. "Are you ready, Alena?"
"..Yes, big sister."
