As a race with high intelligence and magical talents, they were well-known as an inventor of magic. Nonetheless, their birth rate was very low, resulting in having a small number of population which invited other races to destroy them.
Out of jealousy towards the luxuries that the Alvs had due to their magical prowess, the Humans, Elves, and Dwarves attacked and overwhelmed the Alvs using their superior numbers. The Alv subsequently became slaves for trading, and some were violated and gave birth to children which are the Half-Alv.
The Ruquinjé were once Alven royalty, and escaped execution due to their beauty; however, they were instead kept as pets and love slaves by other royalty and powerful figures of the time. They were the masterminds behind the war between the three remaining races to avenge the destruction of the Alv, leading to the high number of casualties estimated to be about the current number of the Elder Tale population, according to ReGan. When the Ruquinjé were found out and about to be killed, the first World Fraction occurred.
Though the Alvs disappeared from existence, their descendants the Half-Alvs, a union between Alvs and Humans, continue to exist in preserving their legacy. Other legacies include magical items like the Mobile Armor, which is used by the Royal Guard, and structures such as the Ancient Palace of Eternal Ice.
Coppelia016 states that the Alvs used "extremely evil rituals," which may or may not be referring to the creation of the demi-human monsters.
- Their name may be derived from alfr, the Old Norse term for (good) elves; the word alv itself is the Norwegian term for elf. However, in the Elder Tale world, the two races are separate from each other.
