Taldeer
Taldeer is an Eldar farseer originally featuring in Dawn of War: Winter Assault expansion and the second expansion Dark Crusade, both times as the leader of the Eldar faction. She is most well known on /tg/ for being one of the protagonists of the awesome piece of writefaggotry known as Love Can Bloom, alongside the Vindicare assassin LIIVI.
In most drawfaggotry not actually directly related to the content of Love Can Bloom, Taldeer and LIIVI are assumed to have somehow escaped from their predicament in Love Can Bloom and are living happily together on Ulthwé or something. They optionally have a child known as Lofn. Taldeer is sometimes depicted as a daughter of Farseer Eldrad, with Macha being her sister. Fellow Farseer Caerys has a bit of a thing for her.
Recently, it was believed that Macha shot and murdered Taldeer in her sleep for being an insufferable bitch. It is unknown whether the story is false, or whether Taldeer was raised as an animate corpse at the bidding of her father. Considering the story took place when Macha was fifteen and doesn't mention LIIVI, more than likely it took place only within Macha's own mind.
It was revealed in Dawn of War 2: Retribution that Taldeer was killed by the Blood Ravens (As told by Azariah as he taunts Ronahn before the Exterminatus). As Ronahn was her brother, the eldar campaign is all about saving Taldeer's soulstone. Which is gay.
And so LCB proved to be canon. How? *Because no one gives a shit about GW's rubbish and never moving storyline, what fa/tg/uys make up is more interesting and actually has some kind of continuation, plus just because Taldeer lost her soulstone, doesn't mean she's dead, she could be like most women and lose important things easily, and kyras would have just said he killed her because he's a douchebag and wanted to piss off Ronahn* *No. It is not. I dunno about you, but I don't think that Commissars rubbing Eldar ears or Eldar having sex with humans is interesting. Finally, that ain't what I meant. I mean how does Kyras having her soulstone prove that she was having an affair with a pussified Vindicare assassin? It just means that Thule riddled her filthy spess elf ass with bolter shells.
In Dawn of War Retribution it is firmly believed that the 'Good End/Epid End' is a combination of the Space marine and Eldar endings. The Blahd Rehvens get their chapter purified, Gabriel Angelos becomes the new chapter master (with even moar manly scars). And Taldeer's soulstone is recovered by her brother and is taken 'home' wherever that is. Though it is likely she'll show up later as a Wraithseer (wraithlord for farseers). It is also known that Lofn escaped before Tadleer's death/soulstone transmition, her current whereabouts are unknown.
However, this will never happen. The Eldar are now quite firmly the new whipping boys for GW. And as such, have failed at everything almost as hard as Failaddon. Srsly, even their own codex hates them.
