The dragons were proud.
However, dragons were not incapable of signing contracts with mortal creatures.
Such contracts were partnership contracts.
The partnership contract of a dragon was a very unique agreement, lasting for five hundred years, granting the contracted party a certain degree of dragon lineage power while also accelerating the dragon's own growth rate.
The drawback was that during the partnership contract period, the dragon's lifespan would be consumed at double the rate.
Generally speaking, dragon partnership contracts were mostly seen from a dragon's juvenile to adolescent period, ending by adulthood.
A dragon's juvenile and adolescent periods combined lasted nearly one hundred and fifty years.
But if a partnership contract was signed, this duration decreased significantly.
The reduction was related to the growth speed and talent of the contracted party, said to increase by more than tenfold at its fastest.
