Go to the pub in Nagapur and talk to Jager standing against the wall by the stairs. He wants to retrieve his summon back but because of the increase of monsters in the area he feels it's too dangerous to go at it alone. Answer positively twice and you will accept the quest. You will then be in the Aqueducts.
Spoiler warning: This section may contain information that could spoil the story line or displays in depth quest or fight details.
A new area - Disposal Tank No. 8 - is available. You'll reach it through the exit at point D-2. Head there and leave to Wyrmskeep. You will immediately battle the Lob Omen. Then battle all of the enemies you see because the Lob Omen hides within their groups (usually groups of Deathclaws). After you killed the Lob Omen 3 more times, you will receive him as a summon (Jager) and the quest will be over.
Tips
Save then use Timeshift to single out the suspected Deathclaw based on the locations below if you don't want to link them. Reload and try another Deathclaw if Lob Omen doesn't appear in the encounter. The Deathclaw tends to act a little bit strange, although it requires some observation to notice.

Finding Jager in Nagapur's pub, you talk to him regarding his problem:
Jager: "Hey. Guess you heard the rumors about that "flying monster," huh? Yeah... Probably ain't a surprise to you, but that "monster" is the Lob Omen. With all the shit going down here in Nagapur, it's been hiding out up at Wyrmskeep. I wanna go up there and get it back, but now that Hermeien's gone, a bunch of monster've moved in. It's dangerous, even for me. Hey, other than that whole sister-kidnapping-and-trying-to-kill-each-other business, we're cool, right? Think you could help me get the Lob Omen back? I heard finding strong Remnants is what y'all are all about lately. So, you down?"
Rush: "Sure, uh, dawg.."
Jager: "Yeahhh, that's what I like to hear. We oughta be able to sneak into the castle through the Aqueducts. C'mon, let's roll."
or:
Rush: "I'm so not "down" I'm up."
Jager: "Hmph, pussy. You don't see me holding a grudge..."
Upon second approach:
Jager: "Whaddaya want? You gonna help me get the Lob Omen yet?"
Rush: "I'm, uh, down with that."
Jager: "Yeahhh, that's what I like to hear. We oughta be able to sneak into the castle through the Aqueducts. C'mon, let's roll."
or:
Rush: "Oh, has hell frozen over?"
Jager: "Hmph, pussy. You don't see me holding a grudge..."
And into the Aqueducts. Upon reaching one of the doors:
Jager: "See? That's where we can get into Wyrmskeep. Can't feel the Lob Omen from here, but it could be hidin' somewhere..."
After beating up the Lob Omen a few times:
Jager: "Geez, it's about time... Sorry for roughin' you up. But it's good to have you back, partner."
And back into the pub we go
Jager: "Hey, 'sup. You really helped me out back with the Lob Omen. Here. It ain't much, but shut up and take it anyway. The hell're you lookin' at me like that for? What, you think I don't know common courtesy? Damn, you're such a little— Eh, whatever. Holla at me later."

Jager wants me to help him find the Lob Omen. It's been spotted near Wyrmskeep, so I should head over to the Aqueducts and make my way inside.
I found the Lob Omen in Wyrmskeep and boy, it looked pissed! I almost had it but it just barely got away. Dammit! I guess I'll have to keep looking.
I got the Lob Omen back. As if there was any doubt that I could! Jager's happy. All's good.
