[40K] Eldread Ulthran "died" in the lore but he's still around? What's that about?

In the original Eye of Terror campaign of Abaddon's 13th Black Crusade back in like 2004 or 05, Eldrad the Eldar Farseer was one of the big casualties. Apparently he tried to steal a Blackstone Fortress but Slaanesh herself was in the fortress. What happened there?

However now he's apparently back and helping out Roboute Guilliman. What happened? Did he escape from Slaanesh and the Fortress or did everything just get retconned?

Well you see Eldrad usually has a plan, he's also kind of a dick. So yeah he probably had an escape plan, a backup plan, and a few other plans in place to get out of the fortress. For all we know Eldrad just convinced some warlock that he was actually him and switched with the double when things went sideways. Perhaps he was never even there and called in a favor from emps to convince everyone that he was? Possibly Eldrad made several clones of himself and uses the clones to confound and confuse his enemies. Maybe papa smurf reached back in time and pulled Eldrad from the fortress before his death?

All we do know is that everything went **just. as. planned.**
