Consanguinity

Two bodies united brought this earth another soul
Born a stem with a deeper invisible mole.
The root of the seed cant be unearthed
His death was written decades before his birth.

Breed of the same kin, a practise since ages
An interest to retain the crown's name in history pages
Piled up disease, morbid bodies through years
Disheveled disabilities of the king who never lears.

So called pure blood running in veins,
Name of his clan for centuries to reign
Wish of a boon for immortality of his lineage
Turned to bane for the tot, till end carrying the baggage.

Gambling with genetics never brought peace
If brought anything to the king a temporary lease.
Never did his kin comprehend the issue's girth
His death was written decades before his birth.
