It's if it's a non-violent punishment, it's still a decidedly harsh move for Iceman to make. Iceman then walks through the gate and leaves them to their fate. The sailors plead not to be left behind, but an unmoved Iceman only provides them with some water, albeit in the form of blocks of ice that they can carry for substance as they walk. Iceman walks through the gate after them, giving them directions towards the city of Sossusvlei, which is roughly a day's walk away. Walking through a Krakoa Gate and speaking with Sage, the pair briefly alter the Gate so humans can pass through it and lead them into the Namib Desert. Since they're in the middle of the ocean and don't have time to deal with them in any legal manner, Kate orders Iceman to take them somewhere "safe" and away. Enraged, the Marauders rescue the people and bring them aboard as well, before turning on the nominal crew of the ship, now revealed to be slavers.
However, Bishop recognizes a message in morse code calling for help and discovers a number of people trapped in cages within the bowels of the ship. After saving the crew and bringing them aboard their ship, the Marauders initially plans to move on and let the ship sink. Along the way, however, they end up coming across a shipping vessel that's under attack from the symbiote dragons and change course to rescue them. The Marauders are some of the heroes venturing into the Knull-controlled New York City, on a specific mission to try and rescue, or take down, the corrupted Cyclops and Storm.
