so i just got the dragonborn dlc and i am wondering how to get to this new place. from what i understand is that i'll be attacked by these dudebros and then i get some note or whatever and that starts the quest. ive yet to see them and is there an alternate way to get there?

EDIT oh and another thing. this is more of a glitch/bug but my companion died and when i try to get another they keep saying "looks like you got someone already". wat do?

You'll have to do the Greybeards quest so they can officially recognize you as the Dragonborn. then the cultists will appear and attack you. the quest is called the Way of the Voice. if you have done that then they will have to appear sooner or later, just keep fast traveling to cities.

thanks for the info. yeah i finished the main quest ages ago. so basically i just have to keep fast traveling to just cities or basically anywhere?
