'complete stage one' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'fiesta embarks off' is the wordplay.
'off' is an anagram indicator.
'fiesta'+'embarks'='fiestaembarks'
'fiestaembarks' with letters rearranged gives 'MAKE FIRST BASE'.

'to' is the link.
