Lldyia

Lldyia, the Silver Dragon, is an NPC mentioned during events but is yet unseen in the Razor's Edge campaign.

Details
All that is known of Lldyia is that she is the elder sister of Lldesh and Lldyr and is very wise. When The dragons' younger brother Alldyn inadvertently caused a family feud by courting a sea serpent, Lldyia quickly disappeared as to remain separate from the fighting. This was likely a wise decision, as Lldesh was left trapped inside the Merfolk Crypt by a curse, and Alldyn's whereabouts are currently unknown.

It is said Lldyia favored her humanoid guise and cared little for troves of treasure as other dragons do. This likely brought her the disdain of Lldyr, and even Lldesh said this was a stance he couldn't agree with.
