Caelum is a magocracy of winged humanoids who inhabit the highest mountain peaks. They are the offspring of the Yazatas, semi-divine beings of an earlier age. Three tribes served the Yazatas in ancient times, the Kavi, the Airyas and the Mairyas. But some were led astray by the wicked Mainyus and Daevas. With the corruption of the purifying flame the Daevas as well as the Yazatas were banished from this world. With the disappearance of the Yazatas the three tribes were dispersed and fled their homelands. But when some Yazatas reemerged from hiding, the three tribes gathered and settled in the high mountain range where the last of the Eagle Kings resided. The former tribes are now known as the Tempest Clan of Spire Horn Mountain, the Raptor Clan of Raven's Vale and the Airyas of High Caelum. The Spire Horn Caelians are partially resistant to cold and lightning. The Raptorians are stronger and attuned to the Earth, but lack the elemental resistance characteristic of the other clans. The Airya once lived in the land of the White Forest where winter lasts for ten months. They still live in the coldest mountain peaks and are unaffected by low temperatures. Their priestesses try to purify the taint of the daevas and are keepers of the sacred flame of the White Forest. The Airya Seraphs craft magical ice that the many Caelians use instead of regular metal. The ice tempers with lower temperatures and the heavy ice armor is more durable in cold climates than in warmer ones. All weapons crafted from the ice are magical and capable of harming magical beings. The Caelians are skilled archers and prefer hit-and-run tactics, even though they do have some heavy troops, such as huge Mammoths.

"Caelum was originally a purely fictional nation of winged humanoids living atop the coldest mountain peaks. Later development has gifted them with Zoroastrian traits. In a Dominions 4 patch, the nation’s backstory was remade and more Zoroastrian traits, summons, and spells were added to the nation. The backstory of a primordial was between Daevas and Yazatas along with concepts of the pollution of the sacred flame merged with earlier ideas of Catharsis/Anthrax. We also added some new guardian spirit mechanics based on Zoroastrian concepts of the soul." -Illwinter

See Magic Access. These guides supplement the summaries at the top.

While EA Caelum has normal magic access using only its recruitable mages, it has plenty of summons with broad path access. Through a pretender, indies, or empowerment, 23 and 3 can get you where you need to be. (Also, 23 can Call Yata for a 1 in 4 chance of 3.)

23 can create a Skull Staff to get to 24. If a different mage can make a Fire booster, you only need 13 to start with.

5 is the goal. 3 can create the Starshine Skullcap to get to 4. If it can make the unique Dimensional Rod, goal reached. If not, Call Celestial Yazad has a 1 in 6 chance of 4. Give the newly called Yazad of the Stars the Starshine Skullcap.

Another option is to start with 23, so that, in addition to the above, the mage can make a Coin of Meteoritic Iron.

Airya Seraphiine has 1. It's a rough climb up.

With 23, Call Yata has a 1 in 4 chance of 3.

With 24, Call Greater Daeva has a 1 in 6 chance of 3 and 2 in 6 chance of 4.
