Hornsent quest

[Tyr]

I have both his map pieces and finished shadow keep except Messmer and can't see any summon signs around the little shadow warriors, I can find him anywhere.

[LuckyCheshire]

The summon signs should be just up the first flight of stairs from the Golden Hippo grace. Try talking to Leda again first.

[palacentes]

did you meet messmer? That might bring hornsent's summon sign inside the bossroom already. Talk to Leda if you havent started her "interaction w other npcs" quest.

[palacentes]

I think if Leda is unable to interact with hornsent, she might choose someone else and have other reward.
