Jedi Prisoner is focussed on recovering a Gree computer from a heavily fortified Sith installation.
It is the first Taral V flashpoint and certainly requires a group with a mean average of 33. The majority of the instance is relatively easy, but the final boss, General Edikar, will challenge an under-level or poorly equipped group.
The mission is start from Republic Fleet, and requires that you take the elevator to Inter-fleet Transport where a shuttle to the Telos is available. Having spoken to Oteg, you will need to use the map to navigate down the elevator and to the Taral V shuttle (at the time of writing the green markers do not show up).
The mission progresses down a jungle path and through 2 different Sith installations. The bonus missions require that all these buildings be eventually cleared, so whilst some parties may elect to clear areas from left to right, generally speaking there is no set order.
The most challenging aspect of this flashpoint apart from the bosses are the jungle creature spawns, where in addition to several normal and a silver difficulty enemy, additional gold elites may spawn in during a fight and require good tank control to pick them up. (gamepedia.com)
