How would you say "The Gatekeeper" in Na'vi?

[ShadowMainZERO]

I am trying to figure this out but I'm not having much luck. I have swapped "gate" with "path" but I can't figure out how to sat something similar to "keeper".  I was going to do something like "the owner of the path" but I can't quite find a good word.

Irayo in advance.

EDIT: I suppose I could use tute and I could attach the suffix -yä. Would that work?

fyahawnuyu

or, more dodgily:

fyaluyu as I say, this is dodgy because I'm asssuming that when -yu is used with lu it assumed to be owner, -tu might be better so it might be fya-lu-tu. Either way though, it'd be dodgy.

Irayo! Now I can get on with the translation! this is going to be very hard...
