They Need That Fragment

Gem narrowed his eyes, the weight of their task bearing down on him. "That's not something that can be done at the moment," he said, shaking his head. "As you know, even the most skilled experts in the Divinity Realm can't get close to the Foundation Pillar, let alone us."

Gem nodded, his lips pursed in contemplation. "I know. But if it's possible, it's worth a try."

Sister Orb interjected, [Yes, getting near the Pillar is enough. With how massive it is, any place where you can at least see it should be more or less sufficient. The Space-Time Realm should be the right realm to resist the force there.]
