As time passed by outside the dwarven frigate, the Golden Skull Alliance had already retracted half of their mechs.
It did not make much sense to keep so many mech pilots in such a stressful position. The Olympus Mons had already exhibited so much power that the humans simply couldn't overcome its might.
If that was the case, they might as well take it easy. They all realized that they had turned into hostages. Since Ves already called in and informed everyone that the dwarves would let them go after a time, the threat of death no longer hung so closely over their heads.
Of course, Ves had declined to mention the difficulty of his task and the consequences of failure. If the expeditionary members knew that the Iron Emperor was willing to have them all killed if he did not get his way, the oblivious humans wouldn't have relaxed their guard to this extent!
