Nobody really liked the plan Kyle created for the worst-case scenario, but it was literally their last lifeline and the only way all of them could survive.
The Fallen Olymp was not something they had any information about and the Guild Master might be able to catch all of them if something were to happen.
This was something they wanted to avoid, which was why they began to thoroughly investigate the Cave of the Lost Arc.
The Cave was nothing special because there were no beasts, no special ores, no crystals, or anything else of value. Nobody would spend their precious time searching through a cave like that, not if they were sane.
Only Kyle and his people were 'insane' enough to search through the valueless cave that harbored one of the most precious artifacts on Shima.
