After falling into the underground you had managed to make your way through various strange locales, a snowy forest somehow underground, a dark and damp part of the cave filled with rivers and waterfalls, and a volcanic area with raised up rocks and molten magma far down below, you have finally made it to the core, the power plant for the entire underground and here you finally meet a robot you have been seeing since the volcanic area

“Hello Darling, a pleasure to finally meet you”
