So i was playing my BG as usual in the Azerithe map, when the Jailer talked to me before i died.
He told me something about getting closer to his realm of dead and meeting him soon. Like literally the voice of him.
Thats what i heard when i was in the GY. But he started talking before when i reached 0 but my souldbind keept me alive for a lil longer so i couldnt hear all the audio because BG noises.
Does anyone had a similar experience?
Update.
Same BG, Seething Shore when i died he talked again.
Said something like “Unraveled(?) one step closer to my realm…”
Some kind of addon maybe adding a sound file to a certain event.
Do you hear voices often in your head ?
OMG, please do a video recording. I’d like to see this.

It happens when you have that garrosh axe equipped or transmogged.

Thank you!
Mistery solved!
Doesn’t everyone?
One said yes, but one said no. The third voice wants to gather more data.
