Travelling, returning gold to a dynasty (7)
I believe the answer is:
roaming
'travelling' is the definition.
(roaming is a kind of travelling)
'returning gold to a dynasty' is the wordplay.
'returning' is a reversal indicator.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'dynasty' becomes 'ming' (I've seen this before).
'or' back-to-front is 'ro'.
'ro'+'a'+'ming'='ROAMING'
(Other definitions for roaming that I've seen before include "Ranging widely" , "Moving about" , "Roving" , "Using a mobile on another network" , "wandering around" .)
