Back in the castle:
Thud! Eris knocked on Aella's door, "Aella, it's me,"
Aella opened the door, yawning, "Eris, do you need something?"
Eris pulled a small bag and handed it to Aella, "Hold onto this for me. I have work to do,"
"What kind of work?" Aella asked, sensing a faint magic from the bag.
"Investigate something for Arad," Eris looked around and walked into Aella's room, locking the door.
"The god of murder's cult. Arad believes there are some of them in this city as we faced a dracolich last night." Eris explained.
"If that was true, wouldn't it be dangerous for you to go alone?"
"More people would make it harder for us to sneak around," Eris pointed at the back, "Look inside."
Aella looked inside the bag only to see a vial of blood, "That's my blood. I heard strong vampire lords can bring their spawns if they are killed. Arad can't do it now, but I'm sure he will achieve that level in a few years."
What Eris was doing while Arad was out with Isdis and the maids.
