The source of what had kept these ruins trapped was right in front of Su. a larger scorpion with a black and ice blue color. It was clearly the parent to the black shadow scorpions living above. But the ruins had been buried and offered this nest. Therefore, the scorpion had been able to make a nest full of young.
Even without it passing on its ice traits to them, the black shadow scorpions had been able to survive. The mother had been an ice shadow scorpion. Able to control ice and shadow. Hiding and injecting its prey with icy venom that could easily freeze and kill many opponents.
Since Su could feel the deathly aura around such a monster, she knew that its venom would effect her more than the black shadow scorpions. She had to resist such a venom if she wanted to survive. it was very clear that without her armor, when she was struck she would be at a disadvantage.
