Listen to the rumor

Quest Text Do you know what the biggest pitfall someone can fall into?
It's when one cannot accept anything else other than what they believe as the truth.

Summary Eileen NPC Knowledge and Lara both sell potions,
but I think that Eileen's potions are slightly better than those made by Lara.
You know, not all potions are made equal!
I didn't notice it at first, but after drinking potions made by different people
I can definitely say there is a difference in quality.
But, what do you think?
Why don't you go tell one of them what you think?
If you think Eileen makes better potions, go talk to her in Velia.
If you think that both Lara and Eileen make equally good potions, go talk to Lara in Heidel.

Summary I heard a rumor about the caretaker to the steeds of Velia, Lorenzo Murray NPC Knowledge.
Have you seen his hair?
Hehehe. Rumor has it that he hates washing his hair
and he styles his hair like he does to make it less noticeable.
He figures you can't tell whether the stench
is from his hair or from his horses.
If you don't believe me
why don't you visit him to take a whiff?
