Falaen was the deadliest assassin during the Age of Giants, which earned her the moniker of "The Silence". Much of her story is a mystery, she grew up among the Drow and was trained to kill elves, but she (with many others) turned on her giant masters. In the war that followed, Falaen assassinated many key targets, drow and giant alike, such that her name spread terror wherever it was muttered. Despite this reputation, Falaen was never cruel, and was patient to a fault.
It is unclear whether she was an elf or a drow herself, and many Keepers of the Past maintain that she was of mixed ancestry.
