Gipat's Lost Souls

Install the Mountain Wind's Staff at the foot of the ruins and kill several ghostly toads and boars in the circle.

Well, we don't owe them anything, but I have a bad feeling about this place. I must figure out what's going on.
If it's about the ancestral spirits, we should try asking other spirits' advice. Here, take my staff. Use it to trap spirits at the foot of the ruins. Use it on ghostly toads and boars.
At the moment of death, the staff must be near the creature. Don't forget it.

Whatever it is, they're not real spirits. I can see you know this darkness. I've seen it in my dreams beyond the forbidden boundary.
I didn't let it come closer.
Have the spirits ever been alive? Or it's just an evil illusion? I do not know...
I just fear that the Orcish "Spirits of the Ancestors" are nothing but darkness.
And still, I was able to see something. A strange cave filled with darkness. Something light was locked inside it, tied with magic chains. If we find the cave, we'll find the answer.
I've seen the path surrounded by stone pillars with rainbow lightning dancing around them. We must find this place.
