They found the wreck near an old Minmatar relay.

No beacon.
No corpse.
No engine heat.

Only a broken transmission:

```
20 15 11 21 04 01
```

The relay said:

```
DO NOT READ LINE 13
```

So I read line 13.

```
FIB KEY ACTIVE
1 1 2 3 5 8 13 21
```

The numbers were not coordinates.
They were offsets.

Decode rule:

```
Take each number.
Subtract the Fibonacci key.
Convert result to letters.
```

Transmission:

```
20 15 11 21 04 01
-1 -1 -2 -3 -5 -8
-----------------
19 14 09 18 -1 -7
```

Invalid letters.

So I wrapped them around 26.

```
19 14 09 18 25 19
```

Message:

```
S N I R Y S
```

The relay corrected me:

```
WRONG DIRECTION
```

So I added the key instead.

```
20 15 11 21 04 01
+1 +1 +2 +3 +5 +8
-----------------
21 16 13 24 09 09
```

Message:

```
U P M X I I
```

Still wrong.

Then the wreck powered on.

It whispered:

```
MINMATAR CIPHERS ARE NOT READ FORWARD
```

I reversed the original signal:

```
01 04 21 11 15 20
```

Then added the Fibonacci key:

```
01 04 21 11 15 20
+1 +1 +2 +3 +5 +8
-----------------
02 05 23 14 20 02
```

Message:

```
B E W N T B
```

The relay went silent.

Then my ship name changed by itself:

```
TOKUDA DE VINCI
```

The wreck opened one last file:

```
line 13 was not a warning
it was a door
```

I checked local.

There were two pilots.

```
Tokuda De Vinci
Tokuda De Vinci
```

One of us was red.

One of us was already dead.

| Encoding Rule: |
| Write the signal as numbers A=1 ... Z=26 |
| Use Fibonacci numbers as the moving key |
| Reverse the signal before decoding |
| Add the key, wrap around 26 |
| If the message is still wrong, the wreck is not |
| hiding text. It is hiding you. |
