Okay, here’s my first rule proposal, hope it is correct.

Add a new Dynastic Rule to the ruleset titled “Artifacts of Time”.  Give it the following text:

There exists objects, known as an Artifact of Time (AOT).  Artifacts of Time act as indicators of things that have happened in a TL.  Artifacts of Time have their list of properties tracked in GNDT.  They have the following properties:  ‘Name’, ‘Description’, ‘TL range’, ‘Events Linked to’, ‘Current TL or Current Holder’.

A description is what the Artifact of Time looks like.  A TL range is the period in the timeline that the AOT exists in naturally.  Events linked to are all events that may have lead to its existance within its TL range.  If its ‘current TL or current holder’ is not a Traveller, it must be a TL that is within its TL range, this describes where it is and describes it as not having a holder.  If it’s current TL or current holder is a Traveller, then that Traveller currently holds it.

If a Traveller changes the timeline at an event linked to an AOT within or before its TL range, e may elect to modify the artifact’s following properties: ‘current holder or current TL’ , ‘name’, or ‘description’.  If a Traveller changes any property of an artifact, e must post about it on the Blog.

If e elected to modify the ‘current holder or current TL’ property then e must either change ‘current holder or current TL’ to any TL within the TL range or to emself.  E may only change it to emself if e is in a TL within its TL range. This is how you pick up Artifacts of Time

If e elected to modify its ‘name’ or ‘description, and a Traveller’s name is inside the ‘current holder or current TL’ property, the current holder may elect to have it returned to any TL in it’s TL range. 

For example, assume Kevan was to take a ‘Murder Evidence Weapon’ with TL range ‘1440/11/25-1440/11/26’ and event link ‘Marcello’ from the TL 1440/11/25.  Then assume Angry Grasshopper were to travel to 1440/3/3 and change the timeline.  E would then be able to take away the ‘Murder Evidence Weapon’, and put it at 1440/11/25, but not give it to emself, since e is at a TL outside the TL range.  E could also redescribe it to contain the text: ‘Has Angry Grasshopper’s blood on it’, and so Angry Grasshopper may elect to have never removed a weapon with his blood from the timeline, thereby leaving the ‘Murder Evidence Weapon’ with ‘Has Angry Grasshopper’s blood on it’ in 1440/11/25

Artifacts of Time may only be created (have its properties Initialized) and removed entirely by the Arbiter.  After creation, an Arbiter may modify the property ‘current TL or holder’ to any TL within the TL range.  An Arbiter may modify the description or name of an artifact, but in doing so, the Traveller who currently holds it may elect to return it to a TL within it’s TL range.

Note that I am not specifing what Artifacts of Time are for in this proposal.  I am also not restricting re-naming and re-describing rules, though that would probably be a good future addition.

To put it simply, Artifacts are the BlogNomic equivalent of picture of Marty McFly.
