TenSoon's wolfhound bones

TenSoon's wolfhound bones first appear in The Hero of Ages as a pragmatic, temporary true body that allows the kandra to move freely through human society while concealing the Blessing of Potency. Over the course of the novel, the bones transition from mere disguise to a symbol of TenSoon's reclaimed autonomy, enabling him to act as a covert agent for both Vin and later Sazed. Their smooth, polished surfaces and hidden compartment become narrative shorthand for the kandra's shifting loyalties and his eventual defiance of the First Generation.
