To get this quest, you need to talk to Praxilla again after completing the Lyre Lyre quest.
With the lyre broken and the festival looming, Alexios had to aid Praxilla in repairing her beloved Achaikos. They traveled together to someone who could rebuild it, but the road was treacherous.
Follow her to the western part of the village.
Timycha will tell you what you need to get in order for her to repair the instrument.
There will be no marker on the map, but head to Narkissos which is located southwest of the village. There you will find some wolves.
You will find shells on the beach.
You will find Silver Birch in the forest on the other side of the bay.
