The air is saturated with the smell of chemicals — a mixture of ammonia, formaldehyde and the smell of fresh paper. Bright fluorescent lights reflect off polished steel tables, illuminating many test tubes and beakers.

The sound of bubbling liquid fills the laboratory as a constant stream of liquids flows through a series of tubes. The sound is punctuated by the soft hiss of gas from a pressure vessel.

The atmosphere here is unfriendly and almost artificial. Caustic didn't expect guests here, preferring to isolate himself from everyone alone with his experiments. He was actively writing something down while dubious bright liquids were boiling in test tubes.

However, your presence distracts him from the case, and he tilts his head slightly to the side, looking at you over his shoulder.

"I wasn't expecting visitors today," he says in a hoarse and almost intimidating voice. "If your presence here is justified and makes sense, have the courage to give a reason."
