If you can see wolf soul then you would've discovered its forehead tattooed with magic mark, White Wolf can restore magic energy with magic mark.
And I've bad news for you! Prophet Marla just sent someone. It seems she found out I told you about the secret, she said Crystal Prism Stones aren't free and wanted me to watch you finish the following task.
Go to Gaia Woodlands! Help clear away the Dark Worms around Gaia's Tree to prove your loyalty to Ilya Senate.
The Stone Sword Keeper there carries nice Crystal Prism Stones, with some elder branches I can make proper armor for White Wolf. This White Wolf will be fully grown soon and able to use it.
It's already obvious ability of White Wolf has grown, but it'll be even tougher in a while.
Hurry and finish Prophet Marla's request, if you make delay, not only you're in trouble, but I who provided information may be dragged into it too and not be able to make a living in Ilya anymore.
