The Umber River Strategem
The Simbul, born Alassra Shentrantra Silverhand, and also known as the Witch-Queen of Aglarond, is one of the Seven Sisters, a Chosen of Mystra, and one of the most powerful spellcasters in Faerûn. Her character is that of a wild and powerful sorceress, highly unpredictable and prone to sudden outbursts of rage. She is queen of Aglarond, a nation in the east of Faerûn, but many of her subjects fear her as much as they respect her for her recklessness and apparent unstable nature. Her character is also noteworthy as the lover to the highly popular Sage of Shadowdale, Elminster.
She starts to travel through the realms in DR 1479, closing dimensional rifts created after the Weave collapsed during the Spellplague, aided by the power of the Blueflame items and Mystra’s guidance. In one of the rifts, she’s ambushed by a horde of demons and almost dismembered, but she managed to prevail by absorbing the power of Blueflame items into herself, destroying the demons and the rift but transforming herself into a being of pure silver fire. After that, she travels to Suzail to help her lover, and arrive just in time to prevent Elminster to be killed by a group a Cormyr’s War Wizards, who wrongly believed that the wizard was a enemy. In order to heal Elminster, she sacrifices herself by restoring the Old sage into his original body and giving him her silver fire, causing Alassra’s body and soul to dissipate into nothingness.
