I never like D'Hara as a name, though it took me a while to actually know where it came from.
The SMA rules are pretty clear. And their enforcement was zealous and brutal at first. I got a lightning bolt myself for cracking an OOC joke at Toren.
If Dwi is still SMA, then every other realm I've been in contact with for the last two years also was, or was pretty damn close save for a non-standard name or two.
As for "most realms had a basis", well I don't think a single realm on Dwi has RPed that "they took the name at random, out of nowhere". They haven't mentionned what the reason is, but their RP didn't say there wasn't. And since the golden rule of RP is that facts are determined by whoever RPed them first, I'll help you out:
The name of D'Hara was inspired after the name of a local prince in the legends of the native dwili people. Prince Dar of the Hili was the heroic navigator who helped the tribe leave the barren lands of the East after a long drought in order to live a more prosperoud life from sea fishing. He guided the settlement of fishing towns on the isles, and is said to have been honored with a great luxurious tomb somewhere on one of the islands. This is why the islands are sometimes called "Tomb Islands", and why the new kingdom was named D'Hara.
See? RP reason given. This was the reason all along, it's just that nobody ever bothered to actually ask.
*Huge* difference between: 1) failing to state the reason for your realm name, 2) stating officially that the realm name was chosen at random, and 3) naming the realm after something it wouldn't have been named after during the reference period in the reference culture.
