A secret research facility hidden below Oblask Dam had discovered unique specimens dating back thousands of years. However, following many accidents while trying to develop biological weaponry with said specimens, the original scientists left, and a military force had been assigned to the excavation site as caretakers. The dreadful results led the research coming to a halt, and a team of biohazard cleanup forces were deployed. Gregor Lenko, alongside Ilsa Nadir, went in to investigate further, and managed to destroy all records and specimens relating to the project.
