Book V Preview:
The sky was dark but it wasn't night, there was light but it wasn't from the streetlamps. There were no streetlamps anymore, there were no streets in fact. They'd been glazed over with lava that had now hardened to dense, dark, lumpy rock. Streetlamps and anything else on the road or path had been drowned in the torrent of liquid fire, which also applied to anyone who had been unfortunate enough to be out when the attack had happened. It would be impossible to tell how many were dead and who the victims had even been, their remains were lost amongst the rock beneath her feet. Muggles had been hit worse than the magical community, anyone in the Ministry at the time - which had been a decent amount of people considering it had been a work day - had been alright due to it being underground and those in buildings could've used magic to protect themselves from being too badly hurt when they came crashing back down. Not that they were completely without injury and she had no doubts there had been some magical casualties too just like there were muggle survivors.
The buildings didn't even look like buildings anymore, the windows were blown out and the walls were cracked. They all stood crooked from being slammed back down onto the uneven frozen lava, if they were even still standing. Some had been too unbalanced and fallen, some lay there unrecognizably on their sides while others were leaning against its neighbor for support or to bring them both down like dominoes. Some were ablaze in places and some had massive chunks torn out by the dragons, like gaping wounds oozing rubble for blood. The dragons were still there, circling, clawing at or breathing fire on buildings at random although not attacking anyone directly. The fires were what were casting a bloody light on the survivors scrabbling through the streets. There were still a lot less people in Athens then there had been yesterday.
