Each Aschevolk serves under a reaper, and each reaper has at least a single entrance and exit to the underworld - doorways called Gates. Souls are brought through these to find their place in the afterlife, strengthening the reaper and those who serve under them.

However, having different expectations on how things are run and how much to meddle in Humans lives, there's a constant power struggle between reapers as they try to carry on their work. They've created their own organizations, their own temples, called Orders - and thus created sometimes less-than-friendly competition between their Aschevolk. Each Order goes by its own name, and has a different way things are run by its reaper -

Seraphim - A cult-like family that brings humans into their so-called religion, keeping them in close proximities as to easily obtain their souls. The Aschevolk of this consider one another as close as family, assisting one another through any hardships. 

Countdown Cadence - Orderly and business-like, the members of this faction run like work. Souls are meant to be gathered in a timely fashion, detachment from the humans you involve yourself with is to be expected. Aschevolk of this organization tend to live in homes with one another as opposed to with humans, as to further their attachment to the 'product'. 

Wolfsbane - Far and few between, members of wolfsbane blend seamlessly into human society with little help from others of the group. Though they're endlessly loyal to the leader of this faction, they tend to not think much of one another. They tend to be the most involved in ordinary human lives.

The following are the reapers of each order! From left to right: Luci, of Seraphim; Pluto, of Countdown; and Kore, of Wolfsbane.  Lore of them will slowly be released through events, and  you're welcome to let them be relevant in an Aschevolk's story.
