Now, head to Janaki. Her location is marked on the map.
Go back to the House of Daena to find information on Ilyas.
After the dialogue, use the elevator to go up to the Acting Grand Sage’s room.
Talk to Alhaitham there.

Pride and Prejudice
The third sub-quest is Pride and Prejudice.

Now, place the key in the other slot and go back to draw the key from before.
You can proceed ahead as one of the barriers will still be down. Grab both keys.
Use both keys on the two slots to proceed ahead.
You’ll then face some fungi. Take them out.
You will reach an elevator. Use it and just ride it all the way up while listening to dialogues.

Now, head to the center and you’ll see Ilyas waiting for you.
