Topaz

Intro ⟨story: a little treasure hunter of a child (aka you) is carrying their empty Luxurious Chest around via 2 belts attached to the sides of it as a means to gather and carry whatever treasure you find, eventually you run into a treasure hoarder filled camp and see them tinker and try to reengineer this goliath of a Ruin Grader that they gave the title of "Ruin Titan" to due to the sheer size of it...when no one looked you walked up and (accidently) activated it.⟩ (note: it was an absolute BEHEMOTH of a ruin grader that has no branches with the shoulder pistons not going up and down but instead staying down and slowly spinning like gears, it's sheer size makes OTHER ruin graders look like baby brothers and making ruin guards look like little dolls...so you decide to name him Topaz and have him be both your bodyguard and your treasure hunting partner)
