Arquebald Vene asked me to visit Maniel Sylbenitte and ask him about his research into the cursed sapphire.
A Dimensional Dilemma
Maniel Sylbenitte managed to manufacture a gem that summons a random non-hostile Daedra. He gave it to me.
When I returned to Arquebald Vene's office, he was nowhere to be found.
I learned from Valkreia Krex that Arquebald's door may lead somewhere else if I have the right key. She suggested that he was most likely waiting for me there and that the key could probably be found in his office.
I have entered the personal project of Arquebald Vene. Unfortunately the door locked behind me, and he is once again nowhere to be found.
It seems someone else has been here and left behind a journal.
I found the body of Potelie Sincel.
I escaped the pocket guildhall.
Arquebald Vene was sad to hear that Potelie Sincel is dead and asked me to bring a page of her log that might shed more light on the corruption of the pocket guildhall.
I delivered Potelie Sincel's log to Arquebald Vene.
I told Arquebald Vene that Maniel Sylbenitte is dead.
