Grim stared out the window, watching the palace. The sun was shining on the palace, bathing the capital in golden light. Yet his mind was far from the scenic view before him.
"Tell me more about these realms," he said, addressing the voice directly now that they were alone. "You claim this knowledge will help me learn my great-grandfather's techniques?"

"And these realms contain... what, exactly?" Grim asked.
