Mateo was born Feburary 17th, 1982, to a family of watchmakers. The family soon immigrated to the United States when Mateo was one month old, due to rising tensions between the east and west during the Soviet Union, and a recent job oppurtunity regarding the making of deluxe watches for an American company. Due to this, Mateo has an interesting accent, a combination of Swiss, German, French, and English.
At the age of 26, after he finished college, Mateo went back to Switzerland despite knowing little to nothing of the language. He wished to see his extended relatives, and soon settled into Swiss country life, enjoying the fresh air, open lakes, and beautiful sky. However, after the outbreak and subsequent collapse of society, his relatives became much closer with him, and a small community was formed in the farm. It was great, till roaming bandits discovered the beautiful place, and razed it, massacring all except those who were currently out: Mateo. He was scavenging a nearby barn for seed packets to help make the farm more reliable. When he returned with his bounty, however? There was no one left to feed.
After this incident, Mateo soon became a wanderer, travelling to places he could have only dreamed of: Paris, Frankfurt, Barcelona, Moscow, and eventually, Chernarus. He travelled across Europe for 2 years before finally making it to the Cacausus region, hugging the green sea. After a brief pitstop in Takistan, he ventured forth to Chernarus, seeing the sights of Novigrad before headidng off to South Zagoria, to experience the thrills there.
