This is the other word for sky, and specifically refers to the night-time sky full of stars. It implies poetry and wonder.
ē teteñ ien hēja ñanna jamāonre nīkan jakōnōr ja ñi jōl rā anīstīli;
And they said to each other: We should make a city with a tower that reaches to the heavens.
la sahēññe jāste ñe anīstīli;
His hair was as dark as night.
