Sebastian walked through the Refuge, looking for information about the Shadow Vipers.
Since the gang had made the mistake of teaming up with the Marauders, the rune master decided to hit them first, just to mess around and test the mana regen ring.
Besides, Sebastian wanted to make things easier for him. It was clear that the gangs didn't trust each other. It has been like this for a long time, and for sure it was when he came to Shrosi. That meant Sebastian could take advantage of that.
Sebastian heard people talking as he walked around. The Refuge was full of rumors. Many people were whispering about a crazy "Grave Whisperer" who was killing people and turning them into undead for no reason. Sebastian smiled to himself, knowing these were exaggerated stories about him.
