Mnimis arpaktikos
Arpaktikos are sorted into various classes:
Specter
Specters are part groups, varying in size, that work as a sort of hive mind. They may have distinct "avatars", which may later develop into individuals. There are many common types, like the phauni (or satyrs), or "shadow people".
Individual
Individuals, like previously stated, can be a further developed form of distinct specter arpaktikos, but they may also fall under individual-specific types. They have names and personalities and histories, much like us humans.
... more to be added in the future.
