Stasis Chambers of Bash'ir involves using a key provided to open Stasis Chamber Alpha. This will spawn Thuk the Defiant who is a level 70 Elite. The quest states it is a 5-man, but it is very possible to do 3-man. Thuk offers no significant loot other than the quest item.
You will need:
The Ethereum have a settlement on the northernmost shelf of Blade's Edge Mountains known as Bash'ir's Landing. According to the key tablet, much larger versions of the prisons are kept at Bash'ir's. It should also be noted that the Ethereum refer to those prisons as stasis chambers.
The key tablet grants access to a very specific stasis chamber at the landing known as Stasis Chamber Alpha. Take the key and investigate.
My image will be awaiting your return at Bash'ir's Landing. Speak to me there.

It is worse than I thought... These chambers hold ferocious beasts and creatures from many, many different worlds. They hope to one day command the beasts to do their bidding. We must destroy them all!
