SWTOR Terror from Beyond Operation boss guide with strats for both storymode and hardmode.
Storymode drops Rakata gear and is meant to be defeated by players in Columi/Rakata gear. Hardmode drops Dread Guard gear and it is meant for players in Campaign gear. However, on the PTS we were able to down a few hardmode bosses with a mix of Rakata/Campaign gear.
Hidden chests (give out crafting mats only)
There are two hidden chests we have found so far, one right before Operator IX and one before Kephess.

Second chest Hint: Look to you right after you get to the open
