Dwilight is like FEI now. Its a long sausage shaped map with Morek (Aracea) at the top.
Comparing Morek with Arcaea is utterly ludicrous. Purely from a density standpoint, Arcaea has
three times the characters per region that Morek does, and is better than the average on four out of the seven continents (and the SI barely counts in this). On the remaining two continents, there are a
total of seven realms with higher density, and two of those are one-region realms.
As far as activity goes, Arcaea is pretty much
the mover and shaker on the FEI. Morek is just big. That's literally all it has going for it right now.
Dwilight is as much like the FEI as a paintbrush is like a tulip. Sure, they've got vaguely similar shapes...but other than that, they're completely different.
