Exploring glitched dalaran

I was playing mindlesly today when i tried submittign a simple bug my game errored but it remained active , but some stuff wasnt what it should be....

first i noticed this piece of map missing in underbelly


to explore this further i needed to be able to fly there then just die and go as ghost form right so i did

i tried reaching the loer portion of underbelly and respawn there but i came across this.




does anybody know this area is it somebodys class hall maybe i never seen it and its in the rock part of dalaran
