Tarsina

Tarsina is a fictional kingdom in the non-canonical novel, The Queen's Curse.

History
The kingdom is inhabited by both magical and mortal residents. Long ago, the ancestral queen cast a curse on the entire kingdom where the throne prince or princess must marry a pure magical being on his or her 25th birthday at latest or every mortal inhabitant in the kingdom will die. For generations, many royal members had fought to keep the curse from enacting, though there were also those who worked against them, hoping that by enacting the curse, the kingdom will be free of mortals.

The Queen's Curse
In the latest generation, throne prince Prince Colin sought out a Charmed One, hoping to preserve his kingdom and laid his hopes on Paige Matthews. The curse's loyalists, including Colin's mother, plotted to stop the marriage, but the Charmed Ones managed to gather the entire kingdom's locals and unite their magic to stop the curse once and for all, allowing Prince Colin to marry the one he truly loves: the mortal Corinne.
