Ker'xxan T'korcha

If you refused (or ignored) Redwillow's request to deliver his letter, he will tell you:
 *  Ker'xxan T'korcha: You have no business with me. Go away.
 * You: You claim to know my business, drow?
 *  Ker'xxan T'korcha: I know you are not the halfling's messenger. I foresee no profit from your death. Therefore, we have no business. Be glad of that.

If you accepted his request, however, he will reply:
 *  Ker'xxan T'korcha: The drow's eyes narrow with suspicion. You are not the messenger I was told to expect. Yet, I see the halfling's letter in your hand. It belongs to me. Give me that letter—now!
 * You: Give Redwillow's letter to the dark elf without comment.
 *  Ker'xxan T'korcha: The dark elf scans the letter. I warned Redwillow that I would only deal with a messenger I trusted. But who are you? Maybe you are a spy laying a trap for my people. Maybe you are a bandit who killed Redwillow and stole his papers. Maybe that pompous fool thought one courier was as good as another. It matter not. Redwillow broke our agreement, and you will die now.
 * You: Your paranoia will be your death, drow! (Start the fight)
