Alula was quite adamant in her warning: "They are guarding some sort of big crystal. We chased them off, but they are very dangerous and will hit you with arrows if you whack them with a staff. I almost died to one!"
Most people didn't believe her - gnolls weren't too common and the girl probably just ate some bad rat meat, judging from the two skinned ones that dangled from her staff. Probably no need to take her seriously
