If you do not get RIP on your tombstone then you will automatically be drafted to the skeleton war.
A cursory Google search reveals that approximately 6,316 people die per hour. If only 1% of those are dumped unceremoniously into unmarked graves (thus not getting RIP on their tombstone and earning the peace of the grave) that means that 63 people enter the skeleton war per hour. Roughly 1500 per day. 550,000 per year.
