Luke wakes up with a quick snort in the bar facedown on the counter. He should have known that the Moondrop was going to knock him out. Tabbytha was sitting on his head licking her paws, but quickly hopped down onto the counter when Luke started moving. The barkeep is sweeping the floor as Luke looks up. "Ah, finally came to eh? Your friends checked out a little while ago, and said that they'd be in the marketplace and that they'd be back later tonight."
Luke's head was pounding, but he needed to get up and start finding out all he could about the necromancer's tower. "Thanks. I'm sorry that I passed out on your counter."
The barkeep stopped sweeping and looked at Luke with a smile. "When you said that you'd have an Elven Moondrop I thought you were joking. I kind of figured this might happen, so don't worry about it."
Luke stood up and made his way to the door, and Tabbytha quickly followed suit. He said a few parting words from the doorway. "I'll be back later today for another drink, but this time I'll just stick to ale." He headed into town looking for someone who knows something about the Necromancer's Tower. The sun blared at him, making him squint as his eyes adjusted. He started walking down the street looking for someone that might know something about the tower.
Tabbytha hopped onto Luke's shoulder and sat down. "You know, you drink too much. You have a job to do, and the hangover isn't going to help you fight the fiends that walk this plane."
