Great Migration

Due to the unique Astronomy of Istria, the north and south poles of the planet are in a constant cycle of freeze and thaw. As a result, a large portion of the population migrates between the poles to remain within the sunlight.

The migration from the north to the south typically begins during the month of Mne and ends the following month of Eyimi. The return migration from the south to the north typically begins during Sruka and ends in Beyra.

Migrants typically travel in large groups for protection from wild monsters and bands of thieving raiders. Also, it is common for caravans to hire soldiers as security against such attacks.

Additionally, many Istrians make a living by ferrying migrants across the many oceans of Istria. Those who own ships can make several trips transporting travelers during the migration season.

Permanent cities near the equator benefit from having many diverse peoples travel through them during the migration and have become strong trading centers as a result.
