Aeseos

Aeseos is the name of the large central continent in the World. To the south-east is the second largest continent of Aetia/ Aetios and south of the Mhalukan Peninsula is the smallest continent of Yaethos.

Maesius claimed it would take 10 years to walk from one side to the other, and once you reached the other side, you'd be able to see the sun, believing the sun rested in the far west of the continent.
