The sinking of the northern and southern continent

Geological / environmental event

During this time the northern and southern continent slowly sank to the bottom of the ocean.

At first, the sings were small. The tides slowly rose and the two landmasses shrank little by little. Over the course, the sinking of these continents the tells became more noticeable and impactful. Heavy tremors broke of tiny parts of the continents forming small islands. With every large tremor, the continents would sink a little further. Sinkholes would appear throughout the continents, filling with water and claiming land from within.   In the end, the northern and southern continents were no more. Their existence only remembered by the scattering of the islands that remained.
