After the fight, he will give you a letter, and suggest you investigate Patrick Morkan.
Patrick will tell you that Lerkara recently left, but her belongings are still in her room in the inn.
Lerkara's journal will point you toward the cave of Tulan.
Partway through the cave you will find Lerkara Fel who will tell you that Patrick Morkan is a necromancer and has resurrected his dead wife.
Slightly further on you will find Patrick, and after a brief discussion he will attack. His wife doesn't move very quickly so you can just focus on Patrick. Kill him and return to Lerkara Fel who is upstairs in The Raven.
Lerkara will send you back to Aethan Engar who will now be found in Rathir in the upper city.
Aethan will promote you to docent, give you the Docent's Ring, and your next quest, Shardfall
If you go into Patrick's home and go upstairs, you will find his bedroom. Two notable things are the desk and a chest.
The chest, which is locked with a spell, is full of different types of gems. Although you still have to steal them, they are worth so much money.
The desk, also locked but without a spell, has a couple of notes notes and a book called Life and Death. The book is written by Patrick and tells about his life. He first writes about how his beloved wife died so suddenly. In his grief, he remembers the day of how they met. He was running to the Scholia Arcana's main house in Rathir to take his initiation trial. He took a shortcut that he never used before. Standing on the sidewalk of the shortcut was his soon-to-be-wife, Jane, who was selling flowers. It was love at first sight. He then writes how he subtlety wooed her and how he never made it to his initiation trial.
Across from Patrick's home is a house called the Reed Home. It is all boarded on the outside. Go inside and you will see a mess, but what's most obvious is the pile of rubble on the stairs that contains a chest. Inside the chest, you'll find different things but one thing always stays the same, which is a burned handkerchief. If you look at the description it says that the handkerchief is burned and that it has the initials JM, which could mean Jane Morkan.
