Algan was a female Tantaari herbalist and chemist who lived in the capital city on Daispin. The span of her life is unknown, but when Vem encountered her in 153 ABY, he regarded her as old. Algan was famous among the Tantaari and Human populations of the capital for her skill as a healer, and her poultices and potions made from native plants were sought to cure a variety of ailments and maladies. Less widely known was her fame in the underworld; thieves and killers often employed her expertise in making poisons.
