My Lands: Black Gem Hunting

I did not understand how clan worked and tried to set one up. It is now "being registered"
but i dont want/need it.
i would rather join someone else's clan. but i guess i need to delete the one i started. but i dont see how. I pressed the little x on it but that did nothing
help please

i completed the world fame but am confused as to how to claim the reward, it keeps saying no hero in garrison, ive trained some Calvary and peasants, does it mean an actual hero i hire? that wont be any time soon as i believe i need to complete alot b4 that... will my reward expire or just stay ...
