New Khan quest abandoned/ not possible to join other faction

[Kabal]

hi all,

i have little a problem with the khan quest. i joined the polish faction and played the storyline until the king assigned me the khan quest. at the moment i am too weak to success this mission, so i canceled it. but now i cannot join any other kingdom. do i MUST end the storyline before i can make further progress in the game as vassal?

best regards

Once you start a storyline you cannot become someones vassal.
