Mists of OblivAeon Oblivion reads "1 Damage to each Invader in target land. 1 Fear per building destroyed by this power to a maximum of 4"
If Bringer of Dreams and Nightmares uses this power, does it earn fear for "destroying" buildings beyond Dreamer's normal fear?
"Do you not know that a man is not dead while his name is still spoken?"
- Terry Pratchett, Going Postal
No, since no buildings are actually destroyed.
Similarly, Vengeance of the Dead would not trigger off of anything Bringer of Dreams and Nightmares does.
