Good if you got that far with the quest. i know its a real pain. after that you go to DM west and kill the boss there where you have to take out the elementals around the spires there. after that you will have to go do the ritual its fairly easy. you will have to summon it then watch your back because there will be waves of demons and imps and the demon that come out can be enslaved. there are felguards that come out too have a good priest and preferably do it with people you know or are in a guild with maybe even take another experianced warlock with you that will help your chances of not having to do it again. thats how i had it done although i did not have all the mats i had it summoned for me. after you defeat the waves you will have to take down a dreadsteed that comes through the portal. thats the final part in there then i belive you go turn the quest in then you get your new beautiful epic mount ! : ) goodluck
