Hello!
We have the following colors.
red
blue
green
white
yellow
We have the following directions.
North
South
East
West
Center
We also have the following locations.
Cavern Entrance
Bank
Fishing Hole
Fundamental Magic Shop
Sacred Tree
First of all, let's try to match each star with a color.
We see that the fourth star to fall was not a Primary color. This means it was either green or white. Let's look for a reference to green or white to see which one the 4th star is.
We see that neither the white nor green star fell at the bank. Therefore, this star 4 is not at the bank. Let's look at our information on star 4. We see that white fell one of the first three nights. Therefore, star 4 is green.
Star 4
Not at the Bank
Green
As you can see, we don't have any more information quite yet. We do have some information on the red star, though. It did not fall at the cavern entrance, and it was in the constellation for at least 3 days. This means it was either 4 or 5. As we said before, 4 is Green, so Star 5 is red.
Star 5
Red
Did not Fall in the Cavern Entrance
Now, let's see what else we can discover.
The north star fell on an even numbered day. As you can see, this means either the 2nd or the Green star came from the North.
Let's think about locations for a moment. We know that the white or green star did not fall at the bank. We see that the second star to fall landed at either the bank or the Sacred Tree. But, we also see that they West star landed in the Sacred Tree.
Let's also think about directions. The third star to fall was in the center. The center and east stars fell sequentially, so the east star is either the 2nd or 4th star. Before, we said the 2nd of 4th star came from the north. This means that the 1st and 5th stars came from the South or West.
We also see that the blue and yellow stars were on opposite sides of the constellation. We know that the 1st and 2nd stars are blue and yellow due to elimination. We know that the north star fell on an even numbered day, which is either 2 or 4. This means 2 could be either North or East.
We also see that the center star would not have fallen at Fungimental Magic as it was not a cardinal direction.
We also see that the yellow star most likely landed in the fishing whole, as it could have looked like a yellow rock that scared of fish.
Let's think about each of our stars so far.
Star 1
Blue or Yellow
South or West
Could have Fallen at Sacred Tree (could be west)
Could have Landed in Fishing Hole
Star 2
Blue or Yellow
North or East
Bank or Sacred Tree
Star 3
White
Center
Did not fall at Bank
Star 4
Green
North or East
Did not Fall at Bank
Star 5
Red
South or West
Did not Fall at the Bank
Now, let's think of what landed at the bank. We know red and green didn't, and we know that the western one landed in the Sacred Tree. The thing is, we know the yellow one landed in the fishing hole. This means the yellow one is not west. Therefore, the 2nd star is not East, but it is north. This means star 4 is East, and Star 1 is South. This also means the Star 5 is West.
As you can see, we know that the red star fall at the Sacred Tree, so the second star fell at the bank. We can also see that the center star did not fall at the Fundamental Magic Shop. As you can see, the yellow star fell in the fishing hole. As you can see, star 2 landed at the bank, so star 1 is yellow and star 2 is blue.
If we do so, all we need to discover is the locations of star 3 and 4. We know that 3 did not fall at the Fundamental Magic, so that means 4 did so. This means 3 fell at the Cavern entrance.
Star 1: South, Yellow, Fishing Hole
Star 2: North, Bank, Blue,
Star 3: Center, White, Cavern Entrance
Star 4: East, Green, Fundamental Magic
Star 5: West, Sacred Tree, Red,
Therefore, our answers are shown below.
---------------------------------------------------------------
The 1st star was yellow, came from the South, and fell into the fishing hole.
The 2nd star was blue, came from the North, and fell into the bank.
The 3rd star was white, came from the center, and fell into the Cavern Entrance.
The 4th star was green, came from the East, and landed in Fundamental Magic.
The 5th star was red, came from the West, and fell into the Sacred Tree.
I hope this helps!
