Alyssa saw the wall of darkness that filled the space inside the entrance, knowing it was too impenetrable to be natural. She studied the stone blocks that made up the archway, looking for any inscriptions or other clues that might cast any meaning onto this obvious enchantment. If there was nothing, and as Salla hadn't offered any source of light yet, Alyssa would instead raise the point of her sword and press it gently into the wall of darkness before pulling it back again, to see what effect it would have on the weapon and how the wall of shadow might react.
