You've killed her? Oh, no no no! I didn't want that, not at all! She was an awful witch, but she didn't deserve to die or anything like that. What should I do? Oh well... I guess you did what you thought was the best. Should I reward you? You know, I'll offer you reduced prices in my shop from now on. Just make sure to fend off any assassins coming my way, will you?

With Tilara Danar dead, there's no way Nevusa Falen will see justice now. My perfect plan came to nothing.

Our little ploy worked! Nevusa Falen was indicted! It tells you everything you need to know about these crooked Dark Elves that she could just pay a bounty and walk out a free woman, but at least now her reputation is ruined. When the people of Bal Foyen think of potions, they'll think of me. Speaking of which, I have a few potions for you. Pop by any time you need more and I'll give you a special price. I don't have your money yet, though. Come back in three days once I've made some sales.

I hear the investigation into Nevusa Falen's crooked dealings is underway. That forged letter was a masterstroke, if I do say so myself.

Don't hang around here! Go report to the captain of the guard, Tilara Danar, in the south tower on the east gate.

You placed the letter? Excellent. Now I want you to go to the guard captain, Tilara Danar. Her office is in the south tower by the east gate. She's a fair dealer, for a Dark Elf, so she'll hear you out, I'm sure of it. Tell her that you suspect Nevusa Falen of some less than legal connections. Don't direct her too strongly, and definitely don't say anything about the letter. I already had my friend make one report, so with you making a second she's sure to investigate.

Put it in the barrel just outside Nevusa's shop. And don't forget the gold. Four hundred septims exactly.
