So, another hunt for crystals. This time, these crystals emitted toxic gas, which is why the chimeras had to use high-tech equipment - masks. Somewhat inconvenient, but still better than getting poisoned.
And their surface probably toxic in contact with the skin. However, Irzel's curiosity is stronger than the instinct of self-preservation.
Oh, this won't end well.
