The Ice Sheet

The Ice Sheet is a post-ML biome that has a portal, which spawns after talking to the Merchant. The merchant will talk about an ice sheet, and the text "You hear the faint noise of a distant portal..." appears in cyan. If you enter the portal, you will be teleported to the Ice Sheet. The portal is always on the left side of the world, just east of the ocean.

Mechanics
The Ice Sheet is a randomly-generated new world. It is completely composed of Ice, Snow, Ice Blocks, and in the edges, Cryofluid. But, what is special about it is that it has 3 phases of progression: Expanding, Halted, Retracting, and Safe. Expanding phase begins at 7:00 PM and ends at 8:00 AM. The Ice Sheet, mainly the ice at the edge, expands. No enemies are here, but Chilled is always inflicted, due to cold weather. It's simply the equivalent of Winter. Halted phase begins at 8:01 AM and ends at 10:00 AM. The Ice Sheet's expansion comes to a stop, and Chilled is cleared out. It's the equivalent of Spring. Retracting phase begins at 10:01 AM and ends at 5:00 PM. The Ice Sheet starts to melt, mainly the edge Ice, and Cryofluid begins to form. Ice Elementals spawn in large numbers in this phase. It's the equivalent of Summer. Safe phase begins at 5:01 PM and ends at 6:59 PM. Retraction and spawning comes to a halt, and Happy! buff is at this phase.

Appearance
The Ice Sheet, at the background, has multiple icy islands in the Expansion phase, a frozen ocean in Halted, some icy islands in Retraction, and only ocean in Safe.

Trivia
- Sunlight is faint in Expanding phase, subtle in Halted and Safe, and intense in Retracting, in the background. - The Ice music plays.
