Maybe slight spoiler
Well actually in the area with all the basilisks, there is a woman turned into stone. If you cast Stone to Flesh on her, she will thank you for freeing her. If you roleplay an evil character you can force her to give you a reward. She then says she has a house near Beregost (slightly to the south of it) and gives it to you. However, there's still nothing you can do with it.
That was your Bit of Useless Information for today, enjoy!
