She came in the night, no one was prepared, not that it would matter. We watched from the furtherest tower as she brought with her a storm, and with one swipe of her hand, destroyed the gate to the city. Arrows did nothing, the ballista was a joke. She smashed her way through the city, that serpent's tail lashing about. She must have found what she was looking for, greedily consuming our strongest wizards and witches, sorcerers, and spell casters in general. I don't know how many disappeared into that black maw of hers but she knew where they were.
After that, a light appeared in her hand. That was it. With one spell, one magical blast, a flash of light, and the whole city was reduced to nothing but a pile of smoldering rubble. We're fortunate to have been where we were at the edge of the city, but there is nothing left for us here. I plead to you, the king, to evacuate all settlements in the area. This "dark mage Echidna" is a monster. She cannot be stopped.
