Ilmo told you somewhat of one of the greater threats to his herd: the Peikkos.
'I spoke to you of the Peikkos which threaten my herd, and I would not bring danger upon someone I know so little, but my concern is urgent.
'These creatures attack my camp in the night, and often I will awake finding one or two of my herd dragged off to some unknown den of the beasts. I can not afford to lose any more elk to these Peikkos.
'Many of these beasts can be found north of here. Go and thin their numbers, and perhaps they will leave me in peace.'
Peikkos can be found north of Ilmo, north of Sûri-kylä.
Ilmo has asked you to drive off the Peikkos which threaten his herd.
Ilmo is outside of Sûri-kylä, north from its gates.
You should return to Ilmo and tell him of your success against the Peikkos.
