The pod appears to be three whales. Their sizes are impossible to describe, given that there's really nothing in the world that compares. What to say of them, other than that they are longer than the tallest trees, wouldn't fit down a standard road, and surely weigh a significant amount even though they are devoid of skin and flesh?
There is a ship in the distance that the whales are currently trying to bring down. They slam at the wooden hull with their bodies, cracking and splintering it. Unable to resist their power, the hull breaks into two and begins to capsize. Screams can be heard, magic used to no avail as the whales open their mouths to try and eat the survivors.
To reach the ship however there are a number of fish and birds in the way, seemingly fighting each other at the surface of the water. Going through them is the fastest way, but something will need to be done to get them out of the way or the boat will take damage. Going around is safer, but will take longer.
