Tim’s new idea regarding the exploration of these lands of ice was quite smart, though it was also simple at the same time. He wanted to have the team turn into ghosts, and simply float through the tens of meters of thick ice below them! They agreed with this plan instantly, as they were tired of putting in tens of hours of work a day only to have no results, so the small risks that came with turning into ghosts was far more appealing in brief comparison.
This idea was bound to be effective, because if there was a burrow filled with dragon eggs down there, they could float into it without having to dig up a quarter of the North Pole in the process. It was a plain, simple plan that he came up with, but it was effective!
