Emperor's Hand does not save SW. One of them asks if they should help and other one answers no, if sw is worthy he/she should survive on his own and get to the outpost in 1 day.

Same here, money got taken from my bank account but purchase is not showing in ledger

Emperor's Voice contains Emperor's full power and is above Dark Council in power multiple times. Emperor (using emperor's voice) even single handedly wiped out all of the Dark Council members at the same time when they tried to overthrow him.

To say I'm disappointed is an big understatement.

Sel-Makor controlled emperor's voice that is only fact, was he weaker or stronger or at same power is speculation and nothing else. Emperor was weakened from previous voice's death when fighting with knight (it was even said in game by Scourge and hand I think ), he was in the middle of essence transfer ritual which was interrupted. Nobody could beat emperor's voice at his full power. So you can't use voice as power comparisson between warrior and knight. Everbody thinks warrior is just brute and not very powerful with force but he was compared with Exar Kun. Inquisitor beats them only with ghosts, without them he is weaker than both knight and warrior.

Not exactly, Wrath is out of system as he was before. He doesn't answer to the Dark Council, nor do they answer to him, only difference is that now there is no Emperor behind him so he has to be more careful not to provoke them to ally against him.

Nox with all his ghosts has more force power than Wrath, but if there is someone that could kill Nox it is Wrath. If you play as more neutral than dark as a Wrath you can have many military commanders, some moff, even some republic guys (unless it goes against republic interests) swear loyalty to Wrath and there is Lord Rathari who has some power base of his own. Kaggath between these two would be interesting to see.

No that's the one in cave, I mean't outside.

If I remember correctly it's the one with puzzles.

Actually, Wrath uses lightning on Yavin IV in SoR during one quest.
