Guided underneath badger's burrow, made oneself at home (7)
I believe the answer is:
settled
'made oneself at home' is the definition.
'guided underneath badger's burrow' is the wordplay.
'guided' becomes 'led' ('lead' can be a synonym of 'guide').
'underneath' means one lot of letters go next to another (in a down clue, some letters go under others).
'badger's burrow' becomes 'sett' (I've seen this before).
'led' put after 'sett' is 'SETTLED'.
(Other definitions for settled that I've seen before include "Agreed; sorted" , "Resolved; calm" , "Resolved (an argument)" , "Colonised; decided" , "no longer an issue" .)
