I honestly don't have any particular reason to think that each of the three has a 1:1 relationship with one of the Biblical "four horsemen." If there is a relationship, in my mind it is more that they are harbingers of a coming catastrophe. I don't necessarily think that Hecarim=war, Thresh=death, etc...
Well, we are discussing a "lack of explicit proof," as you say, and obviously that leaves a lot of room for interpretation. I personally believe that since the other current Shadow Islanders are explicitly stated to have come from elsewhere, the lack of that information for the Trio indicates the opposite. However, I certainly have no basis for saying you're wrong to believe it indicates nothing of the sort! I agree there's nothing to say it has to be, and I hope I've been clear throughout that much of my theorizing about the Shadow Isles is based on inferrences, which obviously do not constitute solid proof by any definition. But if we weren't willing to speculate and spin what we can out of what we have, why are we on a Lore forum
?
| believe that Hecarim has actually been confirmed to have been a member of a long-dead race during one of the AMAs. For whatever reason, his species was completely wiped off the map, perhaps in a way that bears striking similarities to Alistar's tribe |
Anyway, to return to the original topic, I'd argue that the fact that we've even been able to hold this long discussion, with both of us presenting evidence to support two inferred theories, is an indication that enough has been shown of the Shadow Isles to at least make them interesting, even if little is known for a certainty.
