Slayers Exile

Like where do you got to get here?

go to umbrall grotto and its called slavers exile btw

first: go to EotN then travvel north and enter gunnars hold on your right just after the portal. Form there simply ask for a runner of just hh a party and head (south-west) west. youll be there in like 10 minutes maybe more if you plan on fighting some foes on the way.

Umbrall is where you need to be for slavers exile.
Slavers exile is for the last hierophant quest.
The quest will be given to you automaticly after entering the dungeon.
You can only enter the dungeon if you have completed EotN campagne on 1 of your characters.
For questions on the quest check wiki.

hope you got some awnsers now.

Or you can also go to droknars forge and look for my warrior there.
My warrior is there most of the time so you have a big chance of meeting my war, hes very strong and can take lots of trolls there, and lots of armor

"Where do you go to get there" I'm guessing.

Once you've finished eotn, you can get into Slavers' Exile. It's in the south-east-ish corner of Verdant Cascades. Can see it on the map that's linked http://wiki.guildwars.com/wiki/Verdant_Cascades . The nearest outpost is Umbral Grotto, and that's where you'll find PUGs for it if you're after that sort of thing.

Personally, I wouldn't take any shortcuts. I would complete all the missions and quests to get there, in EOTN. It may be important to build up your reputation levels and get all the PVE only skiills that you can only get in EOTN. That's what I did.

rakus right, following primary asuran quest will get you in umbrall grotto too

umbral grotto is the closest city to slavers, but if you have not completed eotn you will not be able to enter the dungeon. big difference
