Hi bcbdrums,
Yeah I made the name myself, awhile ago now. It weren't really that complicated, just did some research and found that:
Mōr = Darkness, Dark, Night.
Morn = Black, Dark.
Norn = Twisted, Knotted, Crabbed, Contorted.
Gūr = Heart (In moral sense), Counsel.
I didn't like the way 'Mornnorngūr' looked, and 'Mōrnorngūr' didn't have the exact meaning that I desired (although close!). Therefore I choose to merge the two, reducing the 'ō' to 'o' and entirely dropping the 'n' from the end.
Now place them next to each other and you get 'Mor-Norn-Gūr/Black-Twisted-Heart', or just 'Mornorngūr'.
I don't know what you make of it, but I am satisfied with it
