The Aslah were the firstborn and were the children of Eradu. They are the gods of the cosmos, immortals with unimaginable power. Though they did not create the substance of the universe - this was created indirectly through Hoth - they have created everything in it: from the trees and flowers and creatures, to men and elves and dragons. All of their creations are born out of the substance of the universe - fire, earth, water, air and positive and negative energy - as indeed they are themselves.

Although imbued with great power and immortality, the Aslah are also flawed. In them are all the flaws that can be seen in their own creations: jealousy, hate, desire and greed, to name but a few. But there is also great beauty as well: love, forgiveness, tenderness and honesty. It is their general nature that draws them together or pushes them apart; the evil Aslah are drawn together, living in one of the many layered hells that the Aslah themselves created: Herophet, the fountain of evil which Gort himself built and imbued with his vileness, or Mulhata, or Talakos. The good Aslah are drawn to Damarkan, which has long stood against the tyranny of evil. Besides Damarkan there are also Paradorn, Wynord, and Henipur.

The shape of Arrasia has been forged by the Aslah, who brought to it both beauty and horror, good and evil. The battles of the Aslah have been fought wherever they or their subjects are found, with the aim of seeking dominion over all others. And though the Aslah are immortal and are not affected by the ever-blowing winds of time, their bodies can be broken and destroyed and their time ended. The spirits of the fallen Aslah rest in Paradorn, where The Keeper of Divine Spirits and his minions serve and protect them and, though many a faithful servant has tried, no Aslah has ever returned from that place.

The clerics of Arrasia associate themselves with a single Aslah, from where their power is channeled. All clerics must be associated with a deity, from whom they receive their spells and domains. Any cleric can only be associated with one Aslah and it is to them that they must dedicate their lives. The Aslah always seek to enhance their flock whenever possible amongst the mortal races and regard clerics as being essential towards this aim.

Of the original nine children of Eradu, only Kavak remains and it is their offspring who now stride the worlds of Herophet and Damarkan. While most Aslah are born immortal, some have been great servants, released of their service and given the status of Aslah. Others still have drunk from the Fountain of the Immortals, through which the tears of Onnus flow. Only those whose heart is pure and whose mind is strong will survive the metamorphosis from mortal to Aslah. And though many have tried, only a few have succeeded.
