Interesting lore note that Dex might cover anyway: our heroes are actually closest to the definition of "horrors". Since we're outsiders, we don't have (at least for now) "affinities" like all characters in Dex's universe proper have, and thus we don't exist on this plane as "real" lifeforms.
Dex's universe proper
Whoop more lore comin' atcha.
As it turns out, it's impossible to make a fan-venture, fan-character, fan-anything in the Daros universe that isn't canon. I lost the image Dex showed me a while ago, but as it turns out Dex's realities and beta timelines and the such have a sort of solar system look to it.
Dex's descriptive image (which I have since lost) shows the "main" reality as a sort of planet in the center, with its beta timelines encircling it like Jupiter's rings. All the "alternate" realities as is defined in any sort of fan-work encircle this "main" reality like the Moon around Earth - each with THEIR own beta timelines. Then each of THOSE "alternate" realities have "alternate-alternate" realities - a fan-work of a fan-work - with THEIR own beta timelines. And that continues ad infinitum in a virtually fractaline nature.
So, really, no matter HOW far-fetched your fan-work is, so long as it is confined to the rules of the Daros universe, it's totally canon. Even if it's a fan-work of a fan-work of a fan-work of a fan-work of a fan---- you get the idea.
What makes the whole Daros multiverse really special is that it's possible to dimension-hop. Anyone in an "alternate" reality can jump into the "main" reality. There's only one caveat...
Lastly, there are the horrors, creatures not normal to the world of Daros. These could be horrible abominations, creeping in from the multiverse to feed on the mortal kin of Daros, they could be random stranded people who got sucked into the multiverse and spat into daros, or even other odd things. If it doesn't fit the other four groups, it belongs here. The one thing they all share in the horror group, is that the universe wants them dead.
Yes, for some supernatural reason, the universe
itself realizes that you don't belong, and will do everything in its power to rid itself of your presence, like a body rejecting an organ transplant. This includes, but is not limited to, earthquakes, meteor showers, thunderstorms, wildfires, tornadoes, and pretty much any act of God you can think of. Universe-hopping might very well be the most dangerous thing that an adrenaline junkie would want to do.
Of course, there's also those who would universe-hop for a vacation, much like any one of us would go to Africa or Disney World or something. As I recall, there's a whole slurry of spells a tourist can use to spoof their way into a universe - like a computer into a remote Local Area Network... probably the very self-same spells that were used on you guys to make sure that the island isn't peppered with meteor showers every half an hour.
Alternatively, just ask yourself: "Does the universe seem to want to kill us?"
