Suggested level: 23
Location: Kaer Morhen
You will receive this quest when you visit the ruins of an old Bastion located west of Kaer Morhen castle.
An observation tower located on a hillside near Kaer Morhen caught Geralt's eye. Though the structure had been there for as long as he could remember, this was the first time in ages he had bothered to inspect it more closely. When he did, he discovered a whole heap of wraiths had taken up residence within. I've said it before and I'll say it again - witchers make horrible housekeepers.
Bastion
Kaer Morhen
In the bastion, you'll come across four wraiths (23) you'll have to get rid of.
At some point your amulet will start to tremble and you will have to use the magic lamp you received from Keira Metz to find out more.
Use the magic lamp received from Keira and find four places where you can see visions of a young boy training to become a witcher.
When you do that, you'll come to the conclusion that the bastion is haunted by a ghost of a boy who trained and died here.
Get on the walls of the castle...
...then go to the tower and you will find the boy's remains there.
Use the lamp again to find out what happened here...
...and then pick up the boy's remains.
A few more wraiths (7) will appear in the castle. Kill them and then bury the boy's remains in the place marked on the map.
Geralt was able to deduce from the evidence at hand that the fortress was haunted by the ghost of a boy who had once trained to be a witcher. His monster slaying career had been tragically nipped in the bud when enraged fanatics attacked Kaer Morhen.
Geralt found and buried the poor lad's remains, and along with them two swords, one of silver, the other of steel. He hoped this would give the boy's tortured soul some peace and allow him to depart from the old bastion.
