Cronus Summoned[]

What have you done?!?

"Hissssss! Who dares to wake me from my slumber? I am Cronus! You? You tiny humans dare wake me? Well you will soon become my dinner!"

Defeat Cronus, The World Hydra before he overtakes you and your keep. Attack Cronus, The World Hydra now! You have summoned the Cronus, The World Hydra, now request for assistance with this battle with a call to arms!

Cronus Slain[]

"ROOOOOOAAAAAAAARRRRRRRRR!" the final hydra head roars as your blade pierces the soft underside of its neck. Cronus writhes in pain and starts to quiver. Cronus's head starts to waver back and forth as it struggles to maintain upright. You gather strength in your tired legs and step back as you fear Cronus might collapse directly onto you. Suddenly Cronus's eyes roll back into the back of its head. The massive body crashes to the ground and creates a thunderous roar that sends shockwaves through the earth.

Cronus lies motionless. It's finally dead! You and your army rejoice. It was a long battle and many good soldiers were lost but the threat is over. VICTORY!!
