Wyvern

Behold Mythical arcane
Fires ignite be thy reign
Feast upon mortal fodder
Arial assault beastly marauder

Fiercely strike despicable foe
Like them, no mercy to show
Brittle tis bones to encrust
Morph minerals to dust

Revenge mighty sapid
Relish pulse so rapid
Flames upon thy hide
Wrath won’t be denied

Avenge ones offspring
Bedeviled tis thy sting
Beware of colossal wyvern
Grave tis meddler's burn
