Keli has figured out why the snow-beasts have been so aggressive recently and wants you to kill their matron.
'Well, my fine ${RACE}, it would appear that there is method behind the recent madness of the snow-beasts. The peikko have been stirred up, you see, by the return of the great snow-matron.
'I thought her existence was a bit of a legend, told to us by the Lossoth as a cautionary tale, but it turns out she is quite real. Since she has come back, it is all an honest dwarf can do to make his way through Länsi-ma without having an ice-boulder hurled at his head.
'Do us all a favour, ${PLAYER}: rid Itä-mâ of this threat! I believe she is within the same cave I told you about before: east and up the hill.'
The great snow-matron can be found in the cave east and up the hill from Zigilgund.
Keli has asked you to rid Forochel of the great snow-matron who has been stirring up the peikko.
Keli is at Zigilgund, west of the peikko-cave.
You should return to Keli with news of your victory of the great snow-matron.
