The sinister drow of the Underdark see relatively well in darkness, but still prefer to light their dwellings.
Special waxes, derived from the alien plant-life of the Night Below, assure that flames burn with a dimness suitable to their sensitive vision.
Dark Elf Corner Candles include two standard avatar standing spots, so this item will not scale well.
Animated flames are self-illuminated so they will keep their own color in rooms with colored lighting,
and also fog overriding so that their glimmer is visible from a distance even in rooms with distance-concealing fogging.
Flames are blue, intentionally.
As always, try before you buy.
