After travelling, Beowulf's protecting Hrothgar's backside to get fancy ornaments (9)

'fancy ornaments' is the definition.
'furbelows' can be an answer for 'ornaments' (furbelow is a kind of ornament). I'm not certain of the 'fancy' bit.

'after travelling beowulf's protecting hrothgar's backside' is the wordplay.
'after travelling' indicates anagramming the letters (letters travel around).
'protecting' is an insertion indicator (inserted letters are held or protected).
'backside' suggests the final letters (the letter at the back).
The final letter of 'hrothgar' is 'r'.
'beowulfs' anagrammed gives 'fubelows'.
'fubelows' going around 'r' is 'FURBELOWS'.

'to get' acts as a link.
