Cat and Mouse.

Mercurius saw the pirate ship in the distance. He didn't expect it was just one pirate crew, and he looked a bit disappointed because he thought there would be more of them. He decided to send three of his units to deal with that pirate ship.

He watched as three of his ships went past his at full speed. He wanted to see how a single pirate ship, not to mention that it was just a medium-sized ship managed to sink a big ship. He thought something was fishy, but he didn't see any other pirate ships in the distance.

Dozens of fireballs were released into the sky toward the pirate ship which would be impossible to prevent all of them from hitting the ship, or at least that was what Mercurius thought. The fireballs disappeared into thin air before they could reach the pirate ship. At that moment he realized the pirates on that ship had a Sage with them.
