Time is a luxury that is not afforded to those of us under the employ of Lady Sylvanas. Surely you know this by now.
As a member of the Royal Apothecary Society it is my duty to share my knowledge with my colleagues so that our collective efforts might one day provide The Dark Lady with the New Plague she so badly desires.
Take these findings to Apothecary Renferrel who is stationed at The Sepulcher in Silverpine Forest. Follow the roads to the south from Brill. From the Undercity go southwest.
Ah, how good of Apothecary Johaan to send his research. With so many new developments here in Silverpine, I nearly forgot about the findings coming out of Lordaeron and Tirisfal Glades. Which reminds me, I need to get those samples off to the Necropolis soon.
But you must excuse my rambling. Extend your stay in Silverpine, <name>. We could use an able bodied <class> like you around here.
