The recorded history of Arrasia began when the elves first came to Agat Amood and Layagat emerged as the greatest civilization of its age. Math, literature, philosophy and science all flourished and much of what is now considered to be civilized in nature has its roots in that time and place. The recorded history of Layagat the wider world also began during this time.

The history of the Aslah and of Arrasia is divided into four distinct ages: pre-history, the Age of Layagat (also sometimes known as the Age of Sárat), the Age of Amman and, the present age, the Age of Karnish.

The time of pre-history is long and it is during this time that Kiwani (which would later be known as Arrasia) was discovered by Kavak and Lima, his great citadel, built. Later, the destruction of Lima would spark the War of Chaos that consumed all of the pre-history age. Although much debate still rages about the exact end of the War of Chaos, it is commonly agreed that the emergence of Layagat represents its most likely end, since around this time Uther had brought peace to the southlands and the nations of men were emerging in the midlands.

The Age of Layagat extends for around 500 years. This is also sometimes called the Age of Sárat, as Sárat was the greatest human nation of this age, which dominated the midlands of Arrasia, and this is probably a more appropriate name for the period, since Layagat itself declines around the year 500, whereas the decline of Sárat and the emergence of Amman occur some two-hundred and fifty years later and are contiguous. Nonetheless, the term Age of Layagat remains the more commonly used and this period saw the growth of the nations of men. It is also no coincidence that this time also sees the orcs and goblins, amongst others, pushed aside and forced to make them homes away from the fertile lands of the well-defended nations of men.

The Age of Amman covers the period of the emergence and decline of the evil nation, Amman. After defeating their old enemy Sárat, Amman would slowly consume the nations of the midlands and southlands and, at its peak, stand as the greatest empire yet to emerge in Arrasia. However, Amman was an evil race that looked to Hakkan for their spiritual guidance and the Age of Amman is considered to be a time of great evil, when oppression, war and suffering were the dominant features. This age would last for almost one thousand years.

The Age of Karnish represents the contemporary age and is still young, being less than 300 years old. Karnish emerged after Fandor and Mynax had defeated Amman in the southlands, from where they launched their invasion of Amman, which would eventually see that evil empire defeated and Karnish emerge as the new power of Arrasia. Unlike the Age of Amman, however, this age is one of freedom and prosperity, with trade and opportunity replacing the misery and servitude of the previous one. Karnish is a great nation, but is not without its enemies. In particular, Hith and his orc hordes have emerged as major threats to the peace of the world and Karnish is now embroiled in a longstanding war against their evil neighbor.

The table below, Historic Timeline, gives the histories, and those given in the national descriptions, a context in time. Many historic events placed here are not in fact mentioned elsewhere, as their significance is limited. The timeline itself uses the elven calendar to date the significant events of history. For other calendars, these dates may vary. For instance, the Karnish calendar starts from year 1 for each age, which are labeled AoL (Age of Layagat), AoA (Age of Amman) and AoK (Age of Karnish. So for Karnish historians, the end of the War of Nÿgamär occurred in 90 AoA and the Second Karnish War of Ascendancy occurred in 68 AoK (or just 68 for short, as Karns tend to assume the present calendar is being discussed, unless otherwise specified).
