The Black Cathedral

After asking a passing minstrell about the great cathedral he tells you:
"The cathedral, aah, the great cathedral. Tales of glory and greatness can
I tell you about the cathedral near Certhunia. But those memories are
shaded by the great curse that is put over the cathedral. Rumour is that an
ancient seer forecast great rewards for the daring adventurer who lifts
this terrible curse. Aah to be able to see the cathedral restored in it's
ancient glory...."
