Clearly, the Brain-Devouring Matriarch's crystalline exoskeleton had a myriad of connections with the Crystal Dragon lineage—perhaps the Frost-Seduction Moth in the Ruins of Ice Abyss also had some link with the Brain-Eating Parasites?
The internal conflict at the Redwood Base that year, the confrontation between the five Elders and The Great Elder, was definitely not just a brutal fight within the brain-eating bug's Spirit Energy Network, but there must also have been a struggle for control over the important facilities inside the ruins and various artificial Origin Quality biological controls.
In summary, the battle between dragons and bugs had persisted for who knows how many years, and it was still ongoing to this day.
And this long-standing war was precisely Ian and his companions' opportunity.
Without a doubt, the Crystal Dragon had already noticed its egg had been stolen, and it should be tracking it; it probably wouldn't be long before it arrived here.
