How do you get Hanharr and Disciple in your team?

The disciple is in the sub-level of the Jedi Enclave on Dantooine. You have to go to the Administrator in the Koonda building to get access to it, then he's down there in one of the rooms waiting for you.

You have to be dark sided to get Hanharr, otherwise you get Mira instead. They're both on Nar Shaddaa. I've not played as dark sided myself yet, but you get Mira after you get a message to go to meet Visquis in the Jekk-Jekk Tar, I'd assume you get Hanharr at the same time.

You have to be a girl to get Discipline otherwise you get handmaiden
Right now I am dark side and I am heading towards Jekk-Jekk Tar. Currently I am on Nar Shaadaa Docks, I do not know about how to get Hanharr yet, i'll come back once I have gotten Hanharr!

You get hanharr when you're just about to meet visquis, first you get mira, carry on to where visquis is wuth her, then visquis will capture her, now chase after viquis by going through the door at the back of his chamber and through the maze, you will get stuck. Now you will be in the pit and you have to kill mira with hanharr and let your main character out of the maze. you probably have to be on the dark side to get him, i haven't played as light side yet so i don't know.

You get Hanhar when your in the Jekk Jekk Tar as darkside. Female or male. And you get Disiple in Dantooine Enclave sublevels. You have to be female to get him. Light or Dark, don't matter.

You don't have to be dark side to get Hanharr. You can get either Mira or Hanharr. What changes is if you accept Hanharra's proposal when he intercepts you on the way to the Jekk-Jekk Tar, right before you talk to Visquis. It's that dialogue that decides whether you get Hanharr or Mira. If you accept Hanharr's proposal, you get Hanharr and the cut scene and fight changes in Visquis hide out. If you reject it, you get Mira and have a different cut scene and fight.

Hanharr is nice, but then I didn't succeed in making all my party members jedi/sith. So, if you succeed in making them all jedi/sith, then mira would be stronger. But if non-jedi/sith, Hanharr is stronger than Mira.

How to get Hanharr:
So, on Nar Shadaa after being contacted by Visquiss, you head oit to the docks. Before entering the area, you get a scene eith Atton. Proceed to the docks. Now is the interesting part: if you are not "dark" enough, you will have a scene eith Mira, which basically seals your fate. However, if you are dark enough, after entering the docks you don't get the scene with Mira. Instead, as you go along the walkway, around Fassa, you get to chat with Hanharr. Here, he will propose an offer to cross Visquiss: if you accept it, you will be him in the arena, thus making him a member of your party. If you refuse, you get Mira.
There are no gender specifics, the only requirement is: you have to be a dark side character.

The opposite is true for the Disciple: you have to be a female in order to get him as a party member.
You can find him on Dantooine, on the sublevel of the Enclave's ruins. After you chat with him a bit, you get an option: "you look familiar to me". That settles the path to making him a party member.
