Until Steeran got home, she couldn't figure out who Ceder had in mind as her new teammate.
Could it be the Strategy Group? But I heard they had also flopped several times in the Sain Dungeon. What difference would it make if they brought me along?
As for others... Well, I do know a few Silver Rank adventurers who could be considered elite, but they're all out on distant missions and not in Bed City.
Adventurers earn their living by accepting quests, which come in all shapes and sizes, not necessarily all related to dungeon exploration, and moreover, not many people have the talent for dungeon exploration.
Adventurers like Steeran, who practically live in dungeons, are actually quite rare.
Before Sain Dungeon, her main job was hunting Boss Monsters and clearing Monster dens around the area.
Once you get involved with Sain, it's for life.
