Okeys well I got a few friends together, we tried getting into ED, didn't work so I wondered, how about a whole community. Bam! you guys came straight to my mind!
Ok so ClareFlare said you get there through and instance, not in Azeroth.
Now I'm thinking, the zepplin represents the boat in CoT that blocks and instance, and the instance's shiny green is the represented by the green smoke.
The clues were all metaphors.
Now on the "hints" movie he jumped into the green smoke (instance door thingy blocked by the boat in CoT) and lagged, I havn't actually tried this but it's just what I think.
I wana hear everyones different opinions, lets all put our thinking caps on and pwn this ED!!!
