Brother's Legacy

You've helped me once, so can you just do me one more favor? My brother Hirelinus, who died a while ago, told me he converted all his property into treasures and hid them in a place no one would be able to ever find. I know why he did it, but what's the point of hiding something if not even I, the inheritor, can get to it? The treasures are concealed under the rocks near Belliga Basin. The bitter cold prevents me from going there. Please, help me again. Can you retrieve the Treasures of Herelinus hidden there?

You haven't set off yet. Please retrieve the Treasures of Hirelinus hidden under the rocks near Belliga Basin.

Oh! You did it! I was dreadfully worried barbarians might have dug it up already. Thank you for your efforts.
