@valadaar: There is an upper-limit to what a basic-model orb can hold. Based on what I've read about the Plane of Radiance, I would assume that a basic orb would shatter if exposed to such high-intensity light -- though I leave this up to GM discretion. Certainly 8 hours of that light would be impossible to store without a custom orb (of which there might be a few floating around the world).
@EchoMirage: I actually disagree with you here. While some inventions are the product of accident or divine inspiration, most can be attributed to "Necessity, who is the mother of invention" (Plato). Most tools are conceived of when a smart person has a need for them. Because Lytharian *was* smart and his need was great, I believe that the origin story is entirely reasonable. But thank you for your feedback -- it really gave me something to think about for future submissions. Go to Comment
