Renfaer has given you a flower to plant whose scent is sure to drive away any Wargs that wish to settle in the Old Burrows.
'I have spent a good part of the morning picking fresh shoots of mint for you, ${PLAYER}. The flower has many beneficial properties, including its scent's ability to repel many beasts.
'I believe if we plant high concentrations of mint in the Old Burrows, the Wargs will not dream of returning.'
The Old Burrows are on the western edge of Thinglad, south of Haldirith.
You should plant the mint in soil at the Old Burrows.
Renfaer is at his new watchpost in the centre of Thinglad.
You should return to Renfaer.
