Invasion Point: Azeroth

It all started from some corrupted grain crates delivered to Booty Bay.
People opened them and became mindless zombies.
The plague was just annoying because killing a zombie could make you become one as well... but it was still ok...



Then something strange happened, a lot of Argent Dawn officials came to the major cities and strange crystals appear all over Azeroth, even inside holy places like Stormwind Cathedral.
Argent Dawn healers works 24 hours per day healing people who got the zombie plague and give you quests that send you to kill ghosts, creepy undeads and shadows... a sense of deja-vu takes over me when i landed again in Eastern Plaguelands...



There is even a new zone (the deathknight starting zone) on the south east of the map. A bunch of houses built around a church and a lighthouse...



...I expected to find ghosts here... instead there isn't anything. No life... even critters stay very far away from this place.
Honestly i don't know if they are planning to put some monsters here in the future but as it is now it is quite scaring :| it's just like something destroyed everything leaving only the inanimated stuff like houses and rocks...



And in the end... the flying fortresses came to Azeroth again. I remember when the Naxxramas patch came online... but now the phenomenon is quite bigger because these pyramids are all around... close to the big town, in Tanaris, in the Eastern Plaguelands... everywhere...

What will be the next big thing coming to Azeroth?
