Event Name: Fallen Emperor
Event Locations: Underworld
Required Partner: Larc
How To Trigger: Alone(without a partner, pets and golems are okay) go to the graveyard and touch the tomb stone to be transported to the Underworld where you'll join up with Larc.
Here's What To Do: Find Olbohn's office and ask for the Baptism of Flame. A Shadole will soon appear. Speak to it and it will offer to take you to the Baptismal Chamber. Agree. After the Baptism head down into the Underworld again. New doors have opened so be sure to explore. Eventually you will reach the end of your journey and Larc will ask if you are ready to "serve" his master. Say yes and you will enter the Shrine of Faces. Defeat Hitodama and meet with Drakonis who tells you his tail of woe. Accept his offer and return to the surface. Larc will give you the Skull Lantern Artifact and the event is complete.
