Shock

Soon after Shadow's arrival, Hideous' lair received another unexpected visitor.
A lone guardian came up to the cave entrance and explained that he realized his former clan wasn't right for him right around the time the matriarch tried opening a portal to the Starfall Isles using three bats and a broken bottle. The two lightning dragons immediately knew exactly what clan he was from, partly because of the insane science, but mostly because of the coffee stains on Shock's scales.
Shadow took an immediate liking to the newcomer, not least because he was the only Guardian she'd seen in months, and Hideous was forced to accept another stowaway in his lair.
In fact, he was becoming increasingly convinced the lair was anything but "his" at this point.

Shock's Search ended unexpectedly, at least for the time being, when a young Skydancer hatchling, having lost its mother, showed up mere days after his arrival. He immediately felt that he needed to protect her at any cost, and vowed to remain with Shadow and Hideous for as long as she does.
