The Wandering Shade in the Barrow-downs asked you to deliver the ring you collected to its brother's tomb in Bree.
'Duty done, again,
to rest at last
I yearn.
'So too my brother,
wandering by night.
A spirit lost
brings naught but fright.
'Provide this ring,
show him it is done.
'Then we rest
'neath Moon and Sun.'
The Wandering Shade's brother now wanders through the streets of Bree. If the sun is shining, the shade may be summoned by troubling its tomb; at night, search the alleys for the shade.
A tomb rests somewhere in Bree, and a shade leaves its confines at night to haunt the streets. The Wandering Shade wishes for you to bring his ring to his brother.
