While reconsidering this sentence: 

{'ej not bIQ'a' qoDDaq lengchu'be}

/and he had never actually traveled around it/

I realized that the English translation is a little dubious. 

The German uses "durchfahren" which means to "travel 

through" in the sense of to "travel through (a tunnel)" 

or "pass (beneath a bridge."

And so, I came up with:

{'ej not bIQ'a' qoD(Daq) chIqchu'}

and/or 

{'ej bIQ'a' qoDDaq ghaHtaHvIS poSayDon'e', 

not lengchu'}

The second sentence seems very clunky to me, although 

I'm not sure if the first one is correct grammar-wise. 

Second question: {legh} v {leghpu'}. In the story the only 

chance Poseidon will get to travel the oceans is in the far 

future, in a mythical End of Times. Although for the purposes 

of the story, it _is_ treated like a historical fact. So, my question 

is: can you use {leghpu'} if the event it's referring to (the event 

that brings the hypothetical into the historical) will happen far, 

far in the future?
