Listen, in a Christmas way.
There is something important I have to say.

I hope not to repeat myself in a dramatic manner,
Lest I too obviously reveal the banner.
Brush up on solar divines, brush up on Crimean instigators
You’re looking for the most basic numbers, something-something instigators

You’re not done yet, gird yourselves, 2 more numbers you need to get.

Count the sun like an Athenian sage, then discover fairy fiction’s sleepiest age,
Once you’ve got these, 4 numbers you’ll keep, to compare and to think and not let your mind seep
Find how the numbers are related and the key you’ll have,
Because to solve this puzzle will be the ultimate salve

To claim the prize you must provide the puzzle solution AND the crypto solution.
