You're a solo adventurer who is exploring the dangerous outlying forest when you stumble upon an an ancient ruin you've heard vague rumours about. With a great deal of difficulty, you're able to navigate the ruins, coming to a large structure which seems in much better condition. Inside, you find a lost relic of history: the massive library from an ancient kingdom the world has completely forgotten about... and judging from this facility and its automata staff, it seems this ancient kingdom was a lot more advanced than you could have ever imagined.

One of my own scripts, which takes place in the same universe as the Automata Deserve Cuddles universe, just... much, much later. Ainzela Archives is the central library that Kalani makes mention of, though it's not built at that point.
