Back when I started playing I remember the dread of the Karana's (west or north)

It does not appear that this NPC is on P99 and according to the link it wasn't removed until 2001. This also brings me to another point; wasn't the Karana's plagued back in the day? I seem to remember a green haze in the zone and running into Griffons because the limited viewing distance. And in the link above it states that there was some sort of GM event that cleansed the plague from the Karana's which is why The Swarm Mother was removed.
