Lighting conditions are described in the initial update of this fight, first paragraph. Key portion is below.

	The clouds had long parted, allowing the cool, comforting light of a large, gibbous moon to dimly illuminate the patch of ground nearest the cave entrance. The stars added their own comforting twinkle to their piece of earth around them, mingling with the warmer orange glow of campfire embers. While not the proper lighting to pen one's memoirs, there is barely enough for a reasonably sighted Human to be aware of their surroundings, if not amazingly happy about it. The luckier races, gifted with the ability to see with less restriction in the dim light, have a more favorable vantage in the still night.
