The Talent (слэш)

1920. London’s magical society is dying. Families are shrinking and plague sweeps the streets, turning mages into monsters.
Son to one of the most powerful British families alive, Loki manages Bor & Sons’ holdings, stalks magical aberrations after dark, and avoids Thor’s polo games at all cost.
All that until American millionaire Tony Stark latches onto him as that guy that published crazy shit in a science journal once. As Loki finds out that Stark might hold the key to end Britain’s suffering, it falls to him to convince him to help rather than rebel against another body of government.
If only he did not have to worry about falling in love.
