The Truest Sith Lord
DISCLAMER: The following post contain significant amounts of inference.
I'm not going to make a two page post like Emp here, but Ragnos did have Sadow and Kressh bowing to him. Sadow eventually taught Freedon Nadd. Nadd was able to conquer the strongest planet in the Galaxy after being taught by Sadow. He began training with Sadow after he was not allowed to become a Jedi. Freedon died eventually, but his spirit taught Exar. After some training and the help of some Sith Artifacts, Exar killed Freedons apprentice, the student of Sadow.
If you look at this it shows by just the facts, it shows that Exar was more powerful than Freedon Nadd.
If we expand on this a little, we discover that an unsubstantiated(did I spell that right?) theory has been going around stating that Frredon killed Sadow after he completed his training.
Again, if we examine this without by just what is stated, Freedon is more powerful than Sadow.
We have therefor concluded that Nadd is stronger than Sadow and Exar is stronger than Nadd.
Sadow<Nadd<Exar
This would make it probable that Exar and possibly Nadd achieved a greater strength than Ragnos.
Now lets include inference's to the discussion.
Because Sadow being killed by Nadd has never been confirmed, it cannot be called on as evidence. I actually made a theory in the EU section saying that Nihilus may actually be Sadow, thus completely dissipating the thought of Nadd killing him.
Nadd's spirit was killed by Exar, not Nadd himself. It is generally believed that spirits become weaker with time and that they don't have the strength of the corporeal form to begin with.
This cancels out the statement as fact, Sadow<Nadd<Exar
The still may be more powerful though.
Exar has be repeatedly described as more powerful than Revan or Malak.
Nadd has also been stated as much worse than Revan or Malak.
Ragnos was, as you know, feared by Sadow.
Sadow was the second most powerful Sith at the time.
Sadow led his army to many victories against the Republic.
Sadow destroyed a star with a wave of his hand.
Sadow learned from Simus, and expert Sith Alchemist.
We can also infer that if indeed Freedon defeated Sadow, it was not by much and that Sadow would not have feared him. At least not like he feared Ragnos.
Nadd conquered the strongest planet in the galaxy by himself.
Exar also can't stronger than Freedon by much and was not feared by Nadd.
Exar killed a lightsaber grandmaster, Vodo Bass.
Exar destroyed a star.
Exar led a war against the Republic and would have won if not for betrayals at the least minute.
Exar perserved himself for 4000 years.
Exar was chosen by Ragnos to lead the Sith. It is doubtful that he would have chosen him to be be the one to lead it if he had not felt Exar capable of defeating the Republic. Ragnos would have probably wated for someone more capable to lead the Sith against the Republic if he hadn't thought Exar could do it.
Kressh and Sadow were basically equal. Lets put them as 10 points each. This means Ragnos has at least 20 points because Sadow and Kressh didn't try to detrone him.
Assume worst case for Ragnos and this Sadow<Nadd<Exar applies.
With this as the case, Sadow is weaker than Nadd. He did not fear him though or else he would have stopped teaching him.
I personaly would be afraid of someone who is 25% or more bigger than me if I thought they were coming after me.
Sadow didn't fear Nadd, so Nadd isn't going to have more than 12.5 points(10* 1.25= 12.5. Still well below Ragnos. Enough to have Nadd fear him just like Sadow and Kressh.
The same thing applies for Exar and Nadd. Nadd didn't fear Exar or else he would have stopped teaching him. This means Exar can't beat more than 25% more powerful than Nadd.
12.5* 1.25= 15.625
Exar is also afraid of Ragnos.
If Exar is more powerful than Revan, Ragnos must be also, thus stating.
Ragnos>Exar>Nadd>Sadow and Ragnos>Revan
