Can't help much given what you've already summed up.

On the Spear:
 * Imhotep fights the Brood in 2620 BC
 * His spear is sent to the East at some point (starting the tradition)
 * However, in 114 AD, according to his entry in, Zhang Heng isn't part of any Brotherhood.

That's not much, but (except if the entry didn't mentioned any affiliations to save the mystery), that means that from 2620BC to at least 114 AD, we're only in the prologue of any kind of organized Spear group, and the role is seemingly held by a few individuals. It seems it is only the object that is kept in the East.
