Alad V carries a lot of story significance with his involvement in the Second Dream and beyond, but his story is entirely out of order. He goes from normal, to cured, to infested. Not to mention a lot of that story was locked behind time limited events starting with Gradivus Dilemma, The Hunt For Alad V, Suspicious Shipments, Breeding Grounds, Mutalist Incursions, Tubemen of Regor, and Shadow Debt. I think these should be translated into proper quests. A potential suspicious shipments quest could have nodes appear around Europa like how Dagath's Abyssal mission appears around Ceres. Infested Alad quest could also be moved to a node around Europa. I really think that DE could reintroduce these as some sort of secondary content to an Infested Ship rework or even the Infested Liches. Similar to how Jovian Concord and the Corpus Ship rework touched on both old and new content. I think a lot more time limited events should become quests too, (A Favor For Darvo and Ties That Bind especially come to mind), but Alad's are the most story relevant.
