Old stories would tell how Weavers would kill each other over aesthetic disagreements, such as whether it was prettier to destroy an army of a thousand men or to leave it be, or whether a particular dandelion should or should not be plucked. For a Weaver, to think was to think aesthetically. To act - to Weave - was to bring about more pleasing patterns. They did not eat physical food: they seemed to subsist on the appreciation of beauty.
