I actually like @Neil. It sounds good to me

Oh and what exactly is a Dragon heartscale?

A great kogaan for your service, my loyal subjects. Here are the words which I find suitable to document:

• Daanstrin (adjective) - to be resigned or accepting of one's fate, place, or future
• Sahdrog (noun) - a leader or ruler who is weak or undeserving of the title
• Vein (verb) - to flap the wings strongly as a show of force or intimidation
• Zel (verb) - to permeate through time, to happen or occur retroactively, so as to have always existed
• Lokrein (verb/noun) - to roar so as to announce one's presence or mark one's territory; such a roar
• Stiir (verb) - to bare one's teeth

These words I shall document and remove from my list. More thought is required, and I anticipate your ideas.

Vebo- 13th one, flying through a wind

Deziin- an action that will happen- inevitable fate.

hope im not too late to put in some stuff.

i had originally thought bovul would be great for fleeing from eternity maybe but its already taken as flee. though the dov have mulitiple meanings for things. so maybe Bodezul to fly or flee against fate but literal would be fly fate eternal. 

Lienkluraav could be world cycle as the dov think of this world as an egg. and that another egg would come to pass when this one has ended. i think  it should be shorter but if you think its fine as is then im cool with that. its literal meaning is "world egg join" to join the next world .

If it needs to be closer to lein (and I think that's an important concept to reference), how about neilein?  It's still got the nei- from 'neilaas,' which is survive, so it somehow conveys the continuation of worlds.  Neilaas seems to refer to some disastrous event, so on a grander scale, that could be the cataclysmic world devouring of the world cycle and what comes out of it.

I like the idea behind neilein, but I'm not sure I like the word itself. Lein is a possible root, but it could come from somewhere else, or have no root at all. Think of it as a series of steps:

• Vus "Nirn"
• Lein "Mundus"
• ? "kalpa"

Kalpa: Researching synonyms for the word "cycle", its origins are Greek. The greek word for circle, which is a synonym, is "kuklos". Perhaps something relating to that? It sounds good.

'Nei' by itself might work..

So I played around in the translator for a while, but I keep coming back to 'kor'

Vus, Lein, Kor...I dunno, it just sounds right to me :/

An issue with kor is that it'd be a close homophone with koor "summer."
