At the end of each 'chapter' of The Secret World's main story quests, there's a sequence in which a disembodied voice calls out to you, asking for your cooperation, and pledging power unimaginable.
At the end of Solomon Island, you are given the opportunity to accept or reject this offer. At the end of Egypt, you can seek 'forgiveness' for unnamed transgressions against the voices. After completing Transylvania, you can repair or destroy the prison in which they are presumably trapped.
Does this choice have any impact? Are there different clothing or cosmetic rewards, or even significant narrative or cinematic differences presented based on these three choices? Do any of the options offer more exposition as to who or what exactly these voices are?
