Anastazja is a birth name, as well as Anna Stazioch.
It was Anetrith from a girlfriend Anet (her real name was Karoline), who was also in brotherhood. Giving a name simmilar to the named of a loved one is some kngiht custom in some of knight parties (witch were simmilar to a guild, but smaller and not as organized as my brotherhood is). We took that custom to our brotherhood and hence my name.
Anetrith changed into Anaztazioch after the win over Z'ioch's guild (the name of a rival brotherhood, Z'ioch was its founder and master). So my name was Anet-Z'ioch, but Anet was a female name it was changet to Anats(belonger to Anet...)-Z'ioch. But it has "sZ" in the name that was hard to spell right, and often my name was wrongly prenouced, so it was changed again to Anaztazioch.
I would specify its meaning better if not for my lack in English, I wont even know what i will type in
Short story isnt it ;p
