That moment when "smart" people think. This is way to quiet and easy to be left unguarded.
But at the same time, its an relic that noone knows about or has used it before. Anyone played dead space ? What if its like a marker, its not reviving the dead, its reviving terrors ?
theres also another possibility, providing the treasure is safe and its been cleared correctly. What if the Dragon Slayer Fleet is in hiding preparing to ambush of the weakened Three Legged Crows ? It be incompetence on Three Legged Crows part, But I can see them being incompetent right now.
