Editing Resurgent Eldar Empire (section)

===Mid M40===
* Muirthandril's expedition recovers an ancient Vaul Engine, known to humans as Blackstone Fortress. Spurred by further visions, the forces of the Empire move to secure various other such stations littered through the Orphus Sector of the Segmentum.
* Muirthrandril is not alone in this prediction, and the Eldar find themselves once again faced with the forces of the Unyielding Vigil. The Orphic Wars begin over the seven Blackstone Fortresses abandoned throughout the sector. There are heroes on both sides - the Vigil will forever remember Brother Estram Yorick, Interred after acting as a lone vanguard to his Brothers, and to this day Hemlock ace Jhainen Khaine-Handed is celebrated for her achievements by the Eldar Empire. 
* Seeking vengeance for sins of the Empire's early years and covetous of the Vaul Engines, the Ark Mechanicus ''Wisdom of Mars'' of the Forgespace, accompanied by its attendant battlefleet, arrives to reinforce the Scions' offensive.
* Mynathensar is rendered inhospitable, and its survivors (the living and the enshrined) are evacuated before Autarch Vaeleryss sets the craftworld on a collision course with the nearby world of Provinus IX, annihilating the Vigil forces regrouping there and cracking the planet's mantle.
*Craftworld Yme-Loc arrives on the eastern fringe of the Edar territory, joining the fray and pledging themselves to the Empire.
*The ''Wisdom of Mars'' diverts its attention from the front lines of the campaign to secure orbital dominance over a particular landmass on the planet of Minerva (Sidharre to the Eldar). Its forces are deployed far behind the battle lines on the planet, and they make no move to assist the forces of the Vigil, eventually departing in their majority and leaving barely a token force behind. The Undying will remember this.
* The war concludes with six of the Fortresses in Eldar hands, but the seventh is destroyed in a daring boarding action by Idrias Stern, who fells Muirthandril in the process. The Farseer is saved by the timely intervention of a Solitaire, but much of his body is replaced with wraithbone prosthetics.
* Harlequins of the Midnight Sorrow continue to harass the ''Wisdom of Mars'' well into is return journey.
