Conveniently, they have ships that can get there in not too long. It's really a very fruitful collaboration of tech and magic, here. 

He spends some more time staring at his coordinates while they travel out there. Saturn is a neat planet. He suspects the Velgarth solar system has a gas giant as well, but astronomy is less advanced there and also not something he's specialized in this lifetime. He thinks he wrote a treatise about it once, twelve hundred years ago or so, but the memories don't transmit that well across lifetimes. 

The pilot stops the ship at the indicated location. Gates have tiny tolerances, compared to Andalite hyperspace routing. If the jump location is a million miles off for an Andalite hyperspace route this is very unlikely to delay your journey by more than a few minutes. For this they have to be within a hundred miles of the right point in space.

Leareth taps the energy-generating-machine like a node, and builds the departure threshold - that part is easy - and then slowly, slowly, sloooooowly reels out the search-spell, here then here then here... 

It lands. Somewhere.

He builds the other threshold. It takes a lot of effort, passing the energy down such a long search-path, and he has to get the terminus very solid and overpowered in order for it to successfully stay put when he bends space around it. He tries to do it fast, though, because it'll be detectable and he wants the message explaining it to arrive fairly shortly after the detection. And definitely before anyone tries to blast the other end of his Gate or something. He'll probably survive it because he's in morph, but he doesn't want to test it. 

No one has tried to blast his Gate by the time the threshold is up.

And now there's a hand-sized Gate, milky-opaque and impossible to see through, and the robot can fly through. 

<It felt right> Leareth says to Cayaldwin. He defaults to thoughtspeak in Andalite morph even when he has Mindspeech too, they're more accustomed to their usual kind of telepathy. 

<Well. Then I guess we see if Matirin can pull this off.>

Leareth holds his tiny Gate long enough for the robot to get some sensor readings and transmit its message on loop a few times, and once it's back with data on whether this was, in fact, the Andalite home world, he takes it down and demorphs and flops on the floor. :I am so tired. It had better be a fast Gate when we send Matirin through: 

The data all looks right. <Should be shorter than this one.>

:Good: Are they going to wait here for Matirin to come in another ship or go back and get him? 

They should go back and get him; ships are scarce. Cayaldwin bounces around cheerfully as they fly.

Leareth is too tired to bounce but watches him with a smile. 

When they get back, he asks if Matirin wants Leareth to cross the Gate too and meet the Andalite leadership, or if he'd prefer it to be just Andalites for now. (Either way Leareth isn't going to be in any shape for meetings right away, it's a very tiring Gate especially when he's still getting used to the routing.) 

He expects he'll want Leareth to come through in a couple of days to weeks once he's gotten apprised of the situation and peoples' current thinking and who he should meet and who they'll have to step delicately with.

Makes sense. 

Leareth spends the ride back out to Saturn taking a nap so he'll be rested for the second Gate. 

They wake him up when they return to the spot. 

<I'll see you soon> Matirin says.

:Good luck: 

And Leareth Gates him over.
