The planet they reached looked like a giant ball of fire, no water or land to be seen on its surface from space.

"Welcome to Mustafar, the lava planet." Mark announced as he pulled the ship down to land it on a patch of volcanic rock next to the Naboo star fighter that gave them the signal to find it.

"Hello?" Sean called out as he stepped off of the ship, scanning his new surroundings as he wiped the sweat rapidly beading on his forehead off with the back of his hand.

"You guys betrayed me."

The group whirled around to find Robin standing behind them with his head bowed, lightsaber held deactivated in his hand.

"Robin!" Sean exclaims in relief as he started to jog towards him.

He didn't get very far before Robin used the force to choke him, lifting him high in the air as he looked up.

His pupils were a vibrant yellow.

He had the mark of a Sith.

"Let him down!" Tyler demanded.

"R-Robin pl-ease." Sean choked out, struggling to maintain consciousness as black dots started peppering his vision.

"This isn't you, let him go!" Mark pleaded desperately, not wanting to hurt him.

"Where were you when the temple fell? When I had to watch my master get cut down as he spent his last breath protecting me." Robin snarled as he tossed Sean's body away, causing him to fly a few feet away from him dangerously close to the edge where the lava surrounded them.

Signe darted over and helped him up as he gasped for air.

"We lost our loved ones too." Amy interjected bravely, stepping forward confidently with no trace of fear on her face.

"The Jedi are gone now-"

"We're still here, we still have a chance." Mark reminded him.

"You won't be here much longer." Robin growled as he activated his lighsaber, his ocean blue blade extending out of the hilt.

Sean barely had enough time to activate his lightsaber before Robin charged towards him, fury blazing in his eyes.

"Why are you doing this?" Sean yelled as he ducked to avoid Robin's blade.

"You're always the best at everything you do, you're even a Jedi Master now. Because of you, I never got the chance to get the promotion I deserved." Robin glowered a he circled around Sean with his lightsaber held in a defensive position as he scrutinized him.

"Robin-"

"My name is Darth Dominus." Robin interrupted Sean before swinging at him again, his blade clashing against Sean's.

"I don't want to hurt you." Sean pleaded.

"Then you're weak!" Robin roared as he used the force to take Sean's lightsaber, holding both in his hands as he stormed over to Sean and crossed them in front of his neck.

"This isn't the real you." Sean whispered.

"If any of you make a move, I'll kill him." Robin threatened.

The group froze with their hands hovering their lightsabers.

"Robin..." Sean trailed off, closing his eyes as he braced himself for whatever Robin would do next.

He was surprised to see Robin putting his lighsaber back when he cracked his eyes open, Robin's eyes back to their original color.

"I'm so sorry!" Robin apologized profusely, deactivating Sean's lighsaber before giving it back to him.

"What happened?" Signe frowned in confusion.

"I let my anger, hate, and jealously consume me. After seeing the destruction of the...well, let's just say that I'm not the same person I once was." Robin sighed.

"So after the temple was destroyed, you came to Naboo, then came here?" Tyler chimed in.

"Yeah." Robin nodded in confirmation.

"Why?" Amy cut in.

"I came to Naboo to try and clear my head,and while I was there I got to thinking about things, then the next thing I knew I stole a Naboo star fighter and flew here when I felt a presence in the force on this planet." Robin explained.

"There's still another Sith we have to worry about, we should go." Mark reminded the group.

Together the seven trudged back onto their ship so they could plan their next move, all of them wondering the same thing:

What will happen when they find the Sith?
