Mysterious Counter Attack

After defeating the attackers,they thought that they won the war, but a surprising magic attack came from the opponent ,it was like a blackhole but more powerful.As expected they are not ready in such a counter attack from their opponent.They got sucked in the magical blackhole in which they cant do anything because of its power..Screams and warrior's tears are the only left..they didnt knew that, that was the end of their nations..
