The ship was meant to explore the Antarctic ocean. They travel day and night until they got to the location they were suppose to land but the ice sheets were hundreds of feet high. They thought that there plans were going bad until they saw a crack in the ice. The Captain said "hey, maybe we could go inside there and explore from the inside". His crew did not agree with him but they would not disobey an order.So they went through the crack, they travel until it go so dark they needed a person with a lantern to go to the bow and tell them if anything is going to hit the ship. They travel for an hour until they started to see a little bit of light in the distance and an opening. The crew were happy because they though they were going to the other side of this ice but they were wrong it was just an opening to a cave which had the light coming from the sealing. The captain try to cheer them up by saying "ha, sheer up mate the tunnel still continue through there other end and..." but he was cut short by one of his crew saying "hey there is a city in the bottom of the ocean, look". So everyone went to the edge and they saw what was a beautiful city but was ravage by the sea. Then they notice how there were other ships there, some of them most have been there just some few months. Then they knew they were not the only one that went through there. All of the ships had the bottom destroy like the ice crush them and they were their next victim. The ice pices of around them did not at first try to crush them it just started when they were half way to the other cave in the end that is when they saw the chunk grew bigger, they started to connect with each other until it cover around them. One of the crew said "This look like magic, it must be a defense system of this city". He was right when the ice cover around them it crush the bottom of their ship and at last the ice retreated to see the ship sink with all of his crew to join the rest of the ship in the bottom.
