We are here by order of Varimathras! The mission of the Shadowstalkers is a simple one: spy. Well, spy with a little assassination on the side.
One of my best field agents has gone missing. I haven't heard from him in days, which has left me fearing the worst. No, not death! Death would be ideal. I fear he may have gone rogue... turned traitor even.
His last known location was northern Mightstone Quarry. He was gathering intelligence on the Nerubians. Find him.
He better be dead...
It doesn't get much deader than this... Strangely, the Nerubians did not devour the corpse.
After careful examination you see that Luther's death was self inflicted - deadly poison. Smart. Nerubians won't come near this toxic corpse.
You notice that Luther is holding a journal.
Shadowstalker Luther is located at [40.0, 52.1].
