Author Intro: This is the last in my Heiress series, which starts with the Twelve Zodiac Coins and also has this other puzzle. Checking out these two may be nice for the storyline but will not be required to solve the puzzle that follows. And now...
"I am so sorry about this. This is the last time, I promise!"
You groan inwardly. F.Y.I., the famous and eccentric tycoon, obviously really loved his puzzles. The family fortune left to his daughter, Gwen, was protected behind so many layers of riddles and puzzles that you wonder if it is really worth the effort. Nonetheless, you're the only one Gwen can turn to now...
First impressions count
On the square stage of the world
Play out your answer
The parts of the whole
Reveal the whole of the parts
Enter as they go
Unity is key
Divergence is also key
Note well this advice
Crimson is this clue
And piscine its nature true
Yet needed as well
"So, let me confirm what your father told you," you say. "We have to enter 4 sequences into this keypad, and all we have to go on are these haikus?"
"Yeah, that's pretty much all he told me," Gwen replies.
"And you've tried every string of numbers you can think of that is relevant to yourself?"
"Yes, I have. Nothing works!"
"Okay, let me think." Your annoyance gives way to intrigue as you ponder the haikus... then slowly, but surely, enlightenment dawns. Surely, it couldn't be that simple..!
Is it, really? What are the codes needed?
Added for clarity:
1. The sequences are not necessarily of the same length.
2. You can assume each sequence is entered x-x-x-x-x-'Enter' if it helps. It isn't really important, just a helpful divider between sequences.
3. Only the text within the block quotes are needed, the rest is purely for story.
