War of the Light

The War of the Light, also known as The War for the Light or The Eternal War, was a centuries-long conflict between the @Light Elfs and @Dark Elfs for control of the Light, which resides in the @Ringed Temple of Alfheim.

Centuries ago, the elves were originally all equal. That was until some of their kind discovered the @Lake of Souls along with the Light Well. Soon, those elves began basking themselves in the Light, which became an obsession. Eventually, due to having basked in the Light for a very long time, they turned into Light Elves. To express their new selves, they began delving into art and invention. Because of their newfound power, an age of prosperity among the Light Elves had begun. However, in the Deserts of @Alfheim, where their other kin, the Dark Elves, live, the abundance of life began to wither and die until there was none left. Thinking that the Lake of Souls was not of use for the Light Elves, and believing that they have gone too far, the Dark Elves started to wage war, thus beginning the centuries-long conflict.

Not a lot of details are known about the conflict over the past centuries, but according to @Mimir, control over the Light has switched between each elven race over 230 times.

Freyr's Arrival

At some point in time, @Freyr, a @Vanir God, who has a strong love of Vanir herbs, arrived in Alfheim and accidentally fell into the Lake of Light. Seeing this, the Light Elves believed him to be a god and, thus, began revering him, due to their belief, along with that of the Dark Elves, that he could bring peace between them. Freyr was able to bring control of the Light to the Light Elves for thousands of years. Because of Freyr's influence, total order was brought to Alfheim.

Freyr's Disappearance

When Freyr's sister @Freya married the All-Father @Odin Borson, in an attempt to end the Aesir-Vanir War, Freyr strongly objected the marriage and decided to abandon Alfheim, leaving it to its fate. As a result, the Light Elves, not knowing of the true reason behind Freyr's unexpected and supposed disappearance, began to believe that their lord was lost. Some assumed that he had returned to @Vanaheim while others believed that he had been captured and held in @Asgard, the home-realm of the @Aesir.

The Fight Continues

Taking advantage of Freyr's absence, the Dark Elves, led by their late king Svartáljǫfurr, proceeded to attack the Vanir God's temple, which houses the Light. Without Freyr, the Light Elves were unable to gain the upper hand over their dark counterparts. As a result, the Dark Elves were able to take over and secure control of the Light, covering it with a giant hive. With the Light under their control, the Dark Elves began slaughtering any Light Elf they could find, which forced the Light Elves into hiding.

The Dark Elves remained in control of the Light and the @Ringed Temple of Alfheim for a very long time until @Loki Laufeyson and @Angrboda arrived. They arrived to refill their Bifröst, which was needed to disperse the Black Breath back in Midgard. The Dark Elves and their king immediately welcomed them with absolute hostility and tried to take them down. However, the duo always managed to gain the upper hand. When the two reached the Light, the Dark Elves made a desperate attempt to protect their hive, but they failed in the end. The two gods freed the Light from the Dark Elves' grasp, allowing the Light Elves to return to the Ringed Temple. Upon regaining and securing the Light, the Light Elves began their mission to try and locate @Freyr. As for the Dark Elves, however, they scrambled and went into hiding.
