Kimella once was a member of the High Elf Nobility, her family was specially involved with magic and the divine, this Involvement made them one of the richest and most influent families of Silvanesti, however this involvement also carried some risk. They went to far, in where a unknown evil (I’m not very used to the DnD verse but with my research I choose Lolth, the queen spider as this unkown evil) massacred her whole family, as the only survivor Kimella was a lost and being persecuted by this evil when she was saved and taken care of by the Followers of Helm, The Watcher, the god of protection, vigilance and duty, to which she pledged her faith and loyalty to. Now her biggest objective is to track that unknown evil that follows her and exterminate it.
