Thus, a creature who is gagged or in an area of magical silence…

• Vael never removes their mask. They don’t eat or drink, and they trance instead of sleeping. All of this is because they aren’t an elf at all; they are a warforged, who donned the armor of an elf who aided them in the Last War and whose legacy they seek to honor.
