I have reached the last waypoint before entering Kilrah. Awesome! But the game won't let me enter the planet itself halp wut do.

From the video I looked at I am supposed to kill a certain Prince Thrakhath because I decided against fighting his little duel earlier in the campaign. I see a Hobbes and a seemingly endless supply of fighters, but no Prince. What gives?

I tried cloaking, approaching the waypoint, then mashing the 'J" key. No luck. Uncloaking before pressing 'J' doesn't help either. I tried running towards the planet, putting a good thirty thousand spacemeters between me and the fighters. Nothing. No autopilot, no cutscene showing my descent into the planet, no nothing...

I dont even

What AM I supposed to do here?

You need to kill Hobbes if you didn't chase him down earlier in the game and Thrakhath. Not sure why Thrakhath isn't there but it won't let you go to Kilrah without killing him.

Also you decided correctly if you choose to duel Thrakhath earlier in the game the Victory jumps without you and you lose.
