glimpsing through that reddit thread, it seems like this story is pretty fleshed out in terms of world building.
Pretty nice to read some of these spoilers, even though I can't truely make anything out of them (and don't want to because there is a chance that I'll bother reading it).

Now, it's a little bit sad that you don't get to understand *any* of that in the anime... they could at least have explained Elq a little bit more, not necessarily reveal what she is, but hint at things a bit more.
