"Based on what you told me, once the undead wore the Harmonizers, they became immune to the sun."
"Not exactly." Lith said. "The only thing we know for sure is that they were capable of moving during the day. We met them underground so there's no way to know if sunlight was still lethal or not."

"I know, but I also know that she had no qualms about letting her children roam free despite their unintended flaws." Leegaain countered. "What if she considers the newfound immunity a flaw as well and she works on it while her new and improved undead spread?
