Crack the egg
Every egg hatches with its first meal, so it is born burning. Your first egg costs no $ASHLING. After that, each egg costs 5,000 $ASHLING × the number already born.
Every ashling is an NFT that lives on its own clock. A meal of ETH lights its flame for 72 hours and adds 10,000 points. Points are your claim on the pyre. Let the flame die and it turns to ash, still yours, but exposed.

Every egg hatches with its first meal, so it is born burning. Your first egg costs no $ASHLING. After that, each egg costs 5,000 $ASHLING × the number already born.
A meal is 0.0005 ETH and all of it lands in the pyre. It relights the flame to a full 72 hours, adds 10,000 points and +1 ATK / DEF. Meals are at least 4 hours apart.
Miss the window and it goes ashen. It keeps its points, but it can't eat, duel or ascend, and rivals take twice as much from it.
Within 7 days, rekindle for three meals of ETH or 50,000 $ASHLING. Wait longer and the ash goes cold: anyone can scatter it, and what it earned plus any bond goes back to you.
Ascending pays its share of every closed split in ETH and $ASHLING, then starts it over at zero points and 10 / 10. The bird stays yours. Ascend right after a split.
The pyre is the game contract itself. Nothing leaves it except through ascending or scattering. Every 8 hours anyone can close the split, and what came in since the last one is shared by points.

Pick a rival and take a slice of its points. The cut is 0.5% of the target's points (1% if it's ashen), scaled by your ATK against its DEF. What you see is exactly what lands.
Your first egg is free of $ASHLING. Every egg after that costs 5,000 $ASHLING × the number of ashlings hatched before it, by anyone.
