Speak with Sergeant Altumus at the East Supply Caravan just outside of Honor Hold, to the east.
While the Burning Legion invaded Azeroth, they were also at work here, in Outland. We have tracked their movements over the years, but this latest activity, <class> - well, this is beyond anything we've seen.
Seek out Sergeant Altumus near the eastern supply caravan. She has been monitoring the invaders and may have insights into their purpose.
Be swift - and take care, <name> - the Burning Legion is not to be underestimated.
