Dracheweld
Dracheweld was a world populated by the mighty dragons for many millenia. Other races gradually came to evolve through various cataclysmic events most typically from other pieces of one of its primordial suns energy balls hitting the planets surface. As these many events led to hundreds of new species they all remained enthralled to the dragon clans. TImes were mostly peaceful and the races while under the eternal leadership of the dragon kin were not mistreated. Rather they were given the utmost freedom so long as they goals and actionas aligned with that of the regional clan.The dragons clans throughout their history maintained a loose aliance to ease infighting and weakening of their hold on the planet. However as time went on the black dragons tired of the arrangement and wished to rule over all others. This caused a fracture in the dragon kin alliance and the races pounced into action destroying nearly all the dragons.
In the chaos that ensued unbeknownst to the races the eldest pair of each type of dragon retreated to a nexus of power hidden from the primary plane and only accessible through dragon magic. At the nexus of power the dragons are trapped. Their life strength nearly used in the escape. The eldest dragons were wise and utilized the power to lay and grow a new generation.... and another..... and another. This lasted nearly 1000 years while the races ravaged their planet. They could watch their machinations but do little about it. The dragon kin could also not communicate with one another in this time but not unsurprising all being born of the same power they all progressed relatively equally.
Over this 1000 years the races nearly forgot about dragons and they passed into myth. Legends to scare the youth is all they warranted. Within the last 100 years rumor of dragon sightings throughout Dracheweld began to arise more frequently. They were generally dismissed as plots of enemies or scared peasants. The question none asked was.... what if they are returning....
