High Elves (Warhammer Fantasy)
In Warhammer Fantasy, the High Elves are the original elves and lived on their home circle island/continent/atoll Ulthuan. Then it all went to shit. This is mostly because of hawt magic secks and the Old Ones not closing their god damned warp gates. They ripped open a hole in space/time and Chaos flooded out like a pierced beer can. The first Phoenix King, Aenarion, got his shit together and closed the gate. Then a bunch of shit happened and Aenarion disappeared. Eventually Malekith got butthurt over not being picked the next king over his bro Bel Shanaar and started the Dark Elves. Because the Dark Elves actually knew how to fucking fight they pushed really far into Ulthuan and killed Bel Shanaar. Then Caledor I came up, Cosgrove'd Malekith back to the northern reaches of the New World. Then Malekith came back and fucked his shit up good. Then a bunch of other shit happened, the Wood Elves said 'Fuck It' and retreated into the woods. At this point the High Elves are a dying race where every citizen is a soldier because there's so few left they can't support a standing army.
Fluff
The Golden Time
Golden Time was before the Phoenix Kings. There isn't much fluff that this editor has read that deals with it. Only that Ulthuan's kingdoms were run by the Everqueen who lead out a positive if hippy-driven jive. Then the chaos came and fucked their shit up. The Everqueen's magic was mostly for peaceful shit and her soldiers were crap. The High Elves prayed to their head god, Asuryan, to help them.
Aenarion, the Defender
Aenarion was a world traveller. He heard some crazy shit was happening at home, so he went back. And shit was way more crazy than he heard. So he went to the Shrine of Asuryan to pray. But, as typical of gods, they didn't do a god damned thing. Aenarion said fuck it and jumped into Asuryan's sacrificing fire. He thought that if he jumped in, his god has to do fucking SOMETHING. And it did. He was imbued with the power of Asuryan. He went outside the shrine, saw some Daemons, and fucked their shit up good. He then ran around messing up Chaos like Kobe did to that chick in Colorado. But unlike Kobe, he didn't get away with it. Chaos attacked Averlorn, where the Everqueen lived, and killed the bitch. Her children were lost. Aenarion was pissed. So he went to a far off island and drew a sword from a rock. Except this sword was the Sword of Khaine. And Khaine is kind of like a cross dressing Khorne. So he goes apeshit, kills tons of Chaos, and rescues a witch named Morathi from some Slaaneshi fighters. He marries the chick, and make their home in Nagarythe, one of the kingdoms in Ulthuan. About this time they realized that the only way to stop the Chaos invasion is to shut off their huge vortex in the big lake in the middle of the continent. After a big fight, they shut it down, but can't quite get rid of it. It would have been an epic win. However, Aenerion got a mortal wound. So he ran back to where he got The Sword of Khaine and puts it back in the rock. From there, his body is never found. He's presumed dead.
Bel Shanaar, the Explorer
Crazy thing is, Aenerion had two kids. Malekith, his first, and Bel Shanaar, his second. So you could imagine how pissed Malekith was when his little bro was picked to be the Phoenix King. During this time, Malekith takes all his whining over to the New World and sets up a bunch of colonies and kills off some orcs. He finds the Dwarfs. Bel Shanaar visited the Dwarfs, too, and signed a peace treaty. Yeah, we know how well that went. It's about this time that the Cult of Pleasure begins to spring up. A Slaaneshi cult that was into crazy Slaaneshi things. Malekith found out his mother, Morathi, was a member. Which overall wasn't much of a surprise. Then a few hundred years later Bel Shanaar decides to hold a meeting at the Shrine of Asuryan. Malekith shows up, kills his brother, and jumps through the fire of Asuryan. Asuryan was disappoint. That's when Malekith becomes the Witch King. He proceeded to kill all the princes of Ulthuan that were at the shrine.
Caledor, the Conqueror
Caledor never liked Malekith. And he was one of the only princes not at the Shrine when Malekith killed everybody. Despite how much he and a bunch of other High Elves didn't like Malekith, lots of elves loved him. So a super fantastical fun Civil War started. It went back and forth, but lots of important folks turn to Malekith's side. Hotek, a priest to the elf god Vaul, steals a the super awesome Hammer of Vaul and runs off to join Malekith. This is probably around the time the Ring of Hotek is made, which took a lot of Douchebaggery to form. Caledor fought really hard, and chased a lot of Dark Elves back to Nagarythe. That's when Malekith pulled a 'Just as Planned' and started to mess with the Vortex in the middle of Ulthuan. What Malekith's wizards do is sink most of Nagarythe, and lots of the kingdom to the south, Tiranoc. Laughing, the majority of the Dark Elves load up in their ships and head north. Some Dark Elves remain, and continue to mess up the High Elves. That's when the finish the first of a bunch of defensive citadels to help keep the Dark Elves at bay.
