None of these imply any danger level for the object classes and instead focus on what it takes to contain them and the reliability of containment; Keter doesn't necessarily mean something is extremely dangerous even if most hard-to-contain Skips are that way due to being intelligent and belligerent, and plenty of Safe Objects are still liable to fuck you up if you decide to mess with them. Shame then that Euclid and Keter became so associated with being weird and dangerous that everybody insists on their special snowflake object class instead of picking one that already exists or determining that something isn't really an anomalous object that needs to be kept under lock and key, as the Foundation's supposedly focused on.
See, this is why
the RPC Authority's system is superior.
They have separate containment ratings for actually rating how easy something is to contain or not. Alpha is their equivalent of "safe", stuff that can basically be put into a box and left there, as long as you don't mess with it or trigger its very specific triggers that cause it to become dangerous. Beta has no real equivalent, or, if you want to be pedantic, is for the easier to contain "euclid" anomalies. Basically, its stuff that presents some difficulty and unpredictability in containment. Anything that is sentient/sapient/autonomous gets put here by default. Basically anything that capable of unpredictability or isn't fully understood goes here. Gamma is the actual "euclid" equivalent, and is for those anomalies that are actually difficult to contain, whose containment procedures are "frequently inconsistent, expensive or complex." This is for anomalies that are still not scientifically understood, are actively trying to break containment, is at such a scale that active containment requires a lot of resources. And then we have Omega, which is their "Keter" equivalent", meant for the anomalies that are the hardest to contain or are effectively uncontainable. These are the anomalies that are threat to global normalcy, but that doesn't mean they are inherently dangerous. At this level, containment may focus on simply preventing the spread of knowledge rather than trying to physically contain the object.
See how easy that is? Clear, concise, and to the point.
After that, there are secondary classes that follow the object class, which primarily deal with the anomalies current state and utility, not its containment. There are only three of these: Explained (EX), for things once thought anomalous but now explained with science; Neutralized (NT), for things that were once anomalous, but whose anomalous properties have become inert (neutralized only refers to the anomalous properties, not the state of the object itself); and Utility (UT), for anomalous object actively employed by the RPCA, including anomalies being used
to contain other anomalies. This was formerly its own object class, Theta, which is still used in some older documents.
Once again, clear, concise and to the point. There aren't ten thousand variations of the same class. Its all easy to explain and easy to apply to any situation.
Then, finally, we get to the actual Lethality rating, which tells you how
dangerous something is. White means that an RCP is non-lethal or even beneficial. Yellow is for stuff that is easy to avoid, or only situationally dangerous. Orange, is for stuff that is
capable of being very dangerous, but not guaranteed to display hostility. Red is for the stuff that's constantly lethal, making direct exposure a continuous risk. Purple are the mass killers, capable of wiping out entire populations or killing en masse. And finally, black is for the world destroying shit. The stuff that causes an apocalyptic scenario.
Once again: clear, concise, and to the point.
And just to make things extra easy to understand, there's a separate
Threat and Hazard Code that explains things in pictograms so that you can immediately understand
how something is dangerous.
