The Lost Queens

Once upon a time, in a world of all things supernatural, a curse slowly destroyed all in the two kingdoms of summer and winter. To break the curse, a worthy sacrifice had to come from both kingdoms. The queens had to die. And although this was the only way, the kings and people alike were against it.
However, the queens snuck away to the sacred altar on the border of the two kingdoms and stabbed each other in the heart with their daggers. The kings were blissfully unaware that the queens were no longer in their castles until a sharp pain in their own hearts took over.
The fates led the kings to the queens who were at the door of death. The kings pleaded with the fates for their queens back but they could not do such a thing in this world. However, at the price of the kings lives, the queens could be reborn in another world - a world that previously held no such creatures, a new world to rule at the sacrifice of forever leaving the old till the queens are found and they too wish to return.
The kings readily accepted, took the daggers from the now dead queens hands and committed the same act as their beloved queens who they are now destined to find in another world.
Little did they know it would be twenty one year wait.
