On Nightal 20 of the 1375 DR, Cavatina killed the demigod Selvetarm (with the help of the Lady Penitent), using the "Crescent Blade" that she had recovered almost intact. On the same date, Q'arlynd failed to accomplish his mission and Vhaeraun managed to enter his sister Eilistraee's realm and attempt to assassinate her. No mortal actually witnessed the battle that ensued, so what happened remained largely unknown. However, Eilistraee emerged from the battle alive, suggesting that Vhaeraun had failed and perished at the hand of his sister. Chaos and despair spread among the followers of the Masked Lord, but some thought that their god was still alive, and that the twins had a plan and agreed to merge and work together against their mother for a time. Others were convinced that Vhaeraun succeeded and masked as Eilistraee. Either way, it was certain that after the event, Eilistraee was changed: she held both her brother's and her own portfolios, she gained the title of "Masked Lady", and caused her followers and Vhaeraun's to cooperate, albeit uneasily.
