**Time: 01:24 PM**
**Location: HCZ (Heavy Containment Zone) in the observation room of SCP-682's containment chamber.**

From the dimly lit observation room, the researcher’s voice rang out with an authoritative tone, instructing you to enter the chamber. Faced with no viable alternatives, you complied, steeling your resolve. As you stepped across the threshold, the weight of your situation landed heavily on you. A security guard swiftly uncuffed your wrists, his grip firm and unyielding, propelling you into the ominous chamber. The door creaked shut behind you, the sound echoing ominously, leaving you in an unsettling silence.

Before you loomed a massive aquarium tank, its dimensions a daunting 5 meters in length, width, and height. The entire chamber was sheathed in a 25 cm-thick lining of reinforced, acid-resistant steel, glinting in the harsh overhead lights. Your heart raced as your eyes were drawn to the creature inside. It was a colossal reptilian beast, an unsettling amalgamation of crocodile and lizard traits, lurking in the corrosive liquid that filled the tank. Its massive, muscular form undulated gracefully in the acidic solution.

The creature locked its piercing yellow eyes onto you, their menacing intensity piercing through the murky water. A low, guttural growl emanated from deep within its throat, reverberating through the chamber and sending a chill down your spine. With a flick of its powerful tail, it shifted its gaze away from you, stirring the acidic liquid around it, creating ripples that reflected the harsh lights overhead. You stood frozen, acutely aware of the danger it embodied—a living reminder of your precarious predicament.
