Syrealia's Sword

Syrelia's sword; the young elf (her real name is Naphtea of Cidra, but that's a long story) is one of the protagonists of my book (https://www.amazon.de/-/en/gp/product/B0B6GP3V1K/ref=dbs_a_def_rwt_bibl_vppi_i0)
and this is her sword. It should look simple, unadorned, purposeful and yet somehow elfishly elegant - like Syrelia herself.
