Astronomy

Sun
There is a single sun over Liertak, essentially identical to Earth's sun.

Skanar
Skanar appears roughly the same size as Earth's moon. It is silver, lined with several large black chasms on its surface. Skanar takes 9 days to complete one rotation around the planet.

Zeren
Zeren is slightly smaller, appearing about 0.6x the diameter of Skanar in the sky. Zeren glows bright purple, but appears golden as it rises and sets. Zeren takes 114 days to complete one rotation around the planet.

Elnon
Elnon is about 1.4x the diameter of Skanar. Elnon is coloured deep blue, with white and bright grey stripes that shift across the surface over time; these appear to be clouds. Elnon takes 26 days to complete one rotation around the planet.

Movement of the Moons
Overlapping of two moons is quite common and, while visually interesting, not noteworthy.

Floodmeets
Approximately every 30 years, all three moons overlap at roughly the point of intersection of their orbits. This is called a "second order eclipse" or a "triple eclipse" by scholars. Common folk call this a "floodmeet". Floodmeets cause a large swelling of the ocean, often causing small floods in low-lying settlements.

Floodmeets are marked by celebrations and festivals all over the world. The Dwarven Assembly occurs at the point of the floodmeet. Floodmeets cause the Sea Chasm north of Kop'ran to temporarily sit completely underwater. It is possible to sail over the Sea Chasm during a floodmeet, enabling travel to the Lost Continent of Dulz'sha; this is the only time such travel is possible.

Solar floodmeets
A solar floodmeet occurs when all three moons overlap with each other and with the sun. Solar floodmeets are even more rare than regular floodmeets, occurring approximately every fifth floodmeet. Solar floodmeets cause enormous ocean swelling, which can cause catastrophic damage to low-lying settlements.
