=,= only angela needs the aether to get. you don't require it for qlaya till you start on her death quest or need amity.

so she, shasha, shizu and kanako can be accessed thru underpass.

so maybe an additional 15k for the ancients if in a bundle (charllote, eva and angela cause of all the traveling it also does and going to the moon 2 times)

perhaps a lil more if lending newbies your aether or sub. they drive around as if on a joy ride not knowing where they are going even when you direct them. and if they do know they drive in circles to get there wasting feul. or trade back your machine and there is danamge on it cause they forget to add feul to it.
