I did. Hence why I specified 'in current canon'. "10 real life years" ago wouldn't be very current would it? Pretty much every eldar codex post the EOT campaign where despite the timeline being rolled back before the events of the crusade, Altansar where still around having been freed at some unspecified point. From Imperial Armour 13.
And we shouldnt forget that he is the ruler of a race full of inteligent and cunning dicks ...for a few millenia.
please don't speak his name. he may be awakened :X and regarding eldar watch this: View: https://youtu.be/FyeoBm5QFnA
Shre mi gala unete suhn relaga meunete suhn. (Mon-keigh translation "He's the asshole king of all assholes")
Achievements? Hmm... This may take a moment Maugan Ra: - Whopped a Tyranid Fleet by himself - Drove Altansar from the Eye of Terror like the Millenium Falcon from the Death Star - Is a heavy weapons dude but is a bro with the lightest kid in school, Baharroth Fuegan: - Ate a Daemon Prince for breakfast Jain Zar: - Got killed by a random Night Lord... no wait... - Is known for devotion for keeping the Banshee-shrines clean, and... uh... - Screams at people? Asdrubael Vect: - Gives lots of random presents (like discussed previously) - Known to crash random ships if you say something wrong - Faked his death with a thing called a geldling, then waited to see which of his allies decided to retreat the battlefield, and then dropped a functional and massive star in at those allies that stayed and all his enemies Harlequin Solitaires: - Duel with Greater Daemons... and win Lelith Hesperax: - Be at the top rankings of fighters in 40k... with two ordinary knives, fingernails and her hair. - Sells tickets for people to watch her kill stuff or to go somewhere (say, that imperial world) and watch her kill stuff - Is in the market for videos of her killing stuff everywhere in Commorragh - Teaches kids to not use drugs Illic Nigthspear: - Is lost on a path that is about freedom from the paths, how the heck does that happen?? - Has killed Warbosses, IG officers, and, of course, Necron Overlords - ^Doesn't sell tickets to these occasions... Some have a business sense, others do not. Urien Rakarth: - Seriously trolled the Tau and probably saved a few of their worlds while at it - Has a larder for "raw materials" to Commorragh, just in case - Savours death like wine... no, seriously. He thinks getting himself killed is so fun that people think he is a Phoenix Lord Baron Sathonyx: - Bounty-hunts bounty hunters - Used to get invited in every single seer council for a long time, then the warlocks finally figured out that he was carrying the bones of a farseer all the time. Awkward.... Duke Sliscus: - Trolled a troll named after a Norse god of trolling - Does not teach kids to not use drugs - Kills people for mispronouncing his name - Never wears the same clothes twice - Went on a holiday with Sathonyx and hasn't come back yet Lady Malys: - Wiped an entire planet of ork freebooterz - Stole an STC as a proposal gift for Vect - Is Was married with Vect <<Data not found>> - Found a random guy in a random place, got a random heart out of it, and did the most sensible thing to do when you find a heart: Replaced her own heart with it. But at least she doesn't teach kids to not use drugs. - ^May have trolled, or may have been trolled by Cegorach That's all for now, I got tired. But I may try cover more.
Of all the MANY names you mentioned... only 3 (+) are (true) Eldar. 3 Phoenix Lords (4 with Baharroth) and a Harlequin. Also being the leader of thé largest Cabal in the capital of the Dark Eldar. And the defacto leader of ALL the Dark Eldar for countless ages... with EVERY other Dark Eldar trying to stab him in the back to take his place. That does not make you cunning.. that makes you UBER cunning. And prob. only of the most dangerous mortal beings in the 41st millenia (save for Malys that actiually proved more cunning that him (Astrubael Vect)
Bested a group of Night Lords, including the unofficial company-champion, Xarl from First Talon. Defeated the Soulhunter while having to limp around with a wounded leg and left him to die. Was severely wounded by the Soulhunter with a suicide-attack with explosives. Was eventually killed by dreadnought Malcharion. And in the short-story The Silent Death, she casually dispatches a Hive Tyrant as an afterthought after slaughtering her way through dozens of Tyranids.
