Part of the language-inspirations appear to be based in Insular Celtic.
Urmothar changed to "Mothar Ur" (for grammatical correctness in Irish) means "New Jungle". Sheevra are Irish fairy-creatures. Aos Si (also known as Aos Sith, and Daoine Sidhe) are likely the inspiration for the Aes Sith, who are an unknown clade of Alvarin.
The people of Lykia (the Alvarin and Aes Sith clades) appear to be based off of various creatures such as Fairies, Elves, Nymphs, and so-on. Veela themselves are most likely at least partially related to Vila, which are Slavic fairies/nymphs. Personally? Based on the game's tone I'd assume they have a heavier "Fair Folk" vibe, and not the kinds of fairies we market to children in the modern era.
Lykia is no longer the name of the entirety of the area, and instead the continent is "Urmothar". Lykia is a territory within.
Lykiators presumably come from Lykia.
Somniferum (Opium) comes from Urmothar.
Meliorwoods are apparently certain kinds of Urmotharian trees. Based on the language roots (which in themselves reveal a lot of MO's lore), they're likely "Great/Strong/Big Trees", which kinda makes me think of Avatar's gigantic trees.
Alvarin developed the falling technique, which makes me think of various free-running moves.
Alvarin are more naturally attuned to magic than any of the other clades. Mats mentioned that their "base level" of magical talent was at the point of being able to sense it (know when it's been used).
Rock Golems are in Jotuni simply because they are 'giant' creatures and not because someone splattered himself on a rock (see thread about ridiculous fall damage).
And I maintain that although Alvarin are taxonomically classified as Irminae under Simia the entire clade of Alvarin, along with the Aes Sith and their immediate 'parent' are not phylogenetically related to any others outside it because all of you are from another planet.
That's the Khurite reconstruction of our Lykiator holding-pods. Sometimes they'd get lost and wander the skies of other planets before we recalled them to the right location. Good thing the poor things were in cryo sleep! A recent mishap ended up releasing some in Myrland, and we're far too busy working on our master plan to do much about it.
1. Those housed the other creatures and plants we brought. Some of them are fun, like Somniferum! Others are less fun, like the terror-vines. Not quite sure who signed off on bringing those..
2. Classified, but rest assured it will be for the good of all. Except a few.
If you wish to join our efforts as a foreign ally, I suggest relocating to our continent and bowing before the Sheevra triumvirate. They're in charge, but that's nothing new. Sheevra always have been, even back home.
