[KC] escape, reasons on escape, the world is round

[Jon Burke]

why can you bring back a paladin with escape? a paladin starts nowhere on 
the board so how is this possible? since it is possible, why can't my 
"knight" that starts in the beginning of the game make two knight jumps?

i have a paladin. i then use the world is round. i move to an empty square 
with my paladin and then capture my opponent's bishop. is he allowed to use 
escape? isnt the card the world is round only used to get to the other side 
of the board and not to capture the bishop (paladin is the only card that 
does this)?
