Nerub'ar Secrets

You skim through the pages of the book, looking for anything of importance. On the last page you discover what appears to be frantic scribbling:

Necrolords. At least a dozen by my count.

Farms to west being used as some sort of horrible spawning glade for Scourge.

Row upon row of victims.

I think they're on to me. Made a dash for the hold. I won't be captured alive.

Dreadvenom hemotoxin. If they decide to bite into me, they'll be in for a surprise.

Take this information back to Barthus.
