I have been using the shortened nickname "Lys" for some time. When I entered internet communities with a nickname "Lysandra" twelve years ago, when it was a unique name. Today it is used as a common name and there are several characters named like that. So I became too tired of being asked "Lysandra" whether I am named after a God of War character or if I was inspired by League of Legends.
Time for a change I guess.
