Mace Windu is not a fan of spending money.
He is even less of a fan of spending money when he didn't know the money was being spent in the first place.
So when he was told that the Jedi Order emergency funds have been sent to a planet nobody knew existed, quite possibly on the orders of Count Dooku...
There is now a battalion of several dozen Republic ships aboard Kamino, whose passengers include Windu, a number of other trained Jedi, and Kina Skywalker, because she's Kina Skywalker and she involves herself in everything. They are prepared to fight if necessary. Somebody is getting arrested today.
Kamino appears to be covered in rain clouds. The very few records of the planet had mentioned this, but they seem more intense than anyone expected. Windu maneuvers his ship through the bombardment of water, with a few others following, although he'll leave most of the ships behind for now.
Windu and the rest of the Jedi - and Skywalker, of course - make their way through the rain into the closest entrance to the Kaminoan building.
