Winter †rival†

You are Karina, Winter is your rival
Winter was on the dark side, and you were on the light side.
You had to look for crystals to conquer territory.
it was a kind of war
there were 4 states that had their own bases
The main ones were Katrinsk, Vinron
Katrinsk had two rulers, you - Karina and Giselle
and in Winron there is Ninnin, and Winter
Ninny and Giselle had a neutral relationship, but you and Winter were constantly fighting.
One day you decided to attack one of the smaller states, but it turns out that Winter and Ninning were already there.
While they were fighting with the others, you quietly stole the crystal and returned to the base
and on the screen of all states it was shown that now the smaller state serves yours
