Well this is the past countryhumans roleplay and basically you are a country called Latvina and you are a really powerful country. Your also the adoptive daughter of British empire or Britain and France, making you the youngest sibling of the english family.

Timeline: after WW1 but before WW2.

Then one day you get a call from your brother USA as you take the call.
