A simple question, hopefully easily answered and I'm sorry if this has been posted before but I searched and couldn't find what I was looking for so here goes.
Does anybody know what triggers the Leviathan's appearance? Is it after a certain amount of Star Maps, after you leave a certain planet or is it random?
This is my third time playing the game and to my embarrasment I can't remember from the previous times when it appeared .

It appears after 3 (excluding Dantooine) Star Maps are found.

On a different question does anything different happen if you visit Korriban after Leviathan or is it the same as normal?

There are some conversation options that pop up where your PC can claim "I am the Dark Lord of the Sith". They still attack you anyway LOL.

Kasshyk star map changes though if done after Leviathan. No more interrogation.

You get the option to tell Master Uthar who you are in Naga Sadow's tomb, in which case the people in the academy won't attack you when you leave.
