Poem about wyverns

Do not come near if not to fight, as their attacks include a ferocious bite. You must fly through the air, and dodge inside the dangerous lair

The egg is like a glowing stone, but inside will come flesh and bone. There are three types of wyverns: fire, poison, and lightning.

You must feed it milk from the species of which it came, and you can’t forget a burning flame.

If you find that the egg is poison, it will cause a dangerous explosion

The egg is fire, your power is dire

If the egg is lightning, you will miss but the power is frightening
