What do you guys think of this system for dungeon delving?
>A tribe of fairies live in the city next to the dungeon they are the only one able to interact with it meaning opening the doors between floors and activating the emergency system to get people out of there with a wait of a few minutes.
>They are extremely weak but if they die they are reborn outside the labyrinth they want nothing more than to reach the bottom of the labyrinth but are too weak to do so.
>So they ally with adventurers to explore the labyrinth they serve as their bodyguards and they as lifelines and to activate the elevators between levels.
>If a party loses their fairy they are practically dead as they have no way to escape but people take the risk because the place is an infinite source of wealth if you can manage to return with loot.
Does it sound like it makes sense?
