That Shadowvale Green Elixir

Collect 8 Bottles of Whispering Elixir from Shadowvale, then return to Carolai Anise in Brill.

Before the Scourge invasion, the reclusive village of Shadowvale was known for its Whispering Elixir. Distilled from herbs found only in Tyr's Fall, the elixir was sought by apothecaries, mystics, and poisoners alike even after being banned in the city.

I've had requests from a number of buyers eager to get their hands on some elixir. Travel to the ruins of Shadowvale deep in the Whispering Forest to the west. I'm prepared to offer significant compensation if you can recover some bottles for me.

I trust you did not get lost?

You say there is evil in Shadowvale? I admit, I am not surprised. The forest folk were an odd lot, and they did not care for visitors. Some believe the Whispering Forest itself is cursed, and the elixir distilled from its roots carries that same curse...

...but enough of superstition and rumors, <name>. Thank you for the elixirs. Here, take this as payment.
