Was Shimrra's Coffer Indestructible?Edit

I've been going through The Unifying Force, which is a copy of the original hardcover edition, and I've found nothing to indicate that Shimrra's coffer was constructed of material that would allow it to be impervious, akin to the Well of the World Brain. Is there anything in this novel I've missed to indicate that Shimrra's coffer was indestructible?EUMAN10 02:01, February 26, 2012 (UTC)EUMAN10
