From Hadria; dark one
Xadrian is a modern creative variation of Adrian, which is derived from the Latin name Hadrianus. It refers to someone from the town of Hadria in northern Italy, which also gave its name to the Adriatic Sea. The 'X' prefix is a contemporary stylistic choice used to give the classic name a more unique and edgy feel.
