Classic What is this door? Why is Old ironforge so small?

​ I took a wrong turn and ended up doing a mini exploring adventure. I found old ironforge which i had no clue it existed. The area looks amazing but there are no npcs other than guards. This door is the end of the route, What could be behind it? Did anything exist? Why is it called 'old ironforge'? via /r/wow https://ift.tt/wpAQWlB
