Who is the strongest Dark Lord?

Darth Traya is above Sion, Bane, and Malak, are you mad? She was weak, as a matter of fact, if you convince Kreia to talk about her being a Jedi or Sith, you see a cutscene of her getting owned by Sion.

Top Sith Lords are Sidious, Exar Kun, Revan, Malak, Naga Sadow, and Nihilus, and I guess you could count Vader too

Darth Traya is very powerful, more so than Sion or Revan.

Nihilus deserved to go first or second at least 😛

Anyone who can cut themself off from the Force could beat Nihilus

who can do it lukestar can!

One question: how does the cutting off from the force technique work and what exactly does it do?

Also, can Tholme do it?

Exactly what it sounds like: It's severing the connection to the force.

Wouldn't that just mean that they wouldn't be able to use the force?

It also means they won't be sensed. Until they reconnect they're just dead spots in the force.

But they can be physically seen right?

Yep. They can still fight, too.

I'm actually kind of rusty on the KotOR plot, does Nihilus have eyes or can he only see through the force?

Good question. I'd guess through the Force.

Is this what Tholme can do?
And what book did Luke do it in?

Luke learns the Fallanassi ability in the Black Fleet tril. And yes, this's what Tholme does

Do you know which page?

No clue

hmm.. so who is the strongest dark lord ? nihilus ?

have we decided yet 😛

DE Sidious.
