Sorry JCarter, for calling you Jimmy Carter.
I remember one of the masters saying that even if one of the members sharing a bond die, the bond would still exist but it would be empty, like a wound. So THIS is the reason why the Exile is called a wound in the Force. He carries the empty bonds of the people who he knew and wro died at Malachor. But why did the incident at Malachor specifically "strengthen" the Exile's bonding ability? And how does the Exile "blend with the echoes"?
Vader extinguished lives at Alderan while the Exile did so at Malachor but the reason Vader is NOT CONSIDERED a Wound is that he didn't have strong bonds with the people he killed at Alderan, while the Exile did. Can you explain why Sidious is a Wound in the Force?
