Harner Grinder lived a pretty calm life, he was a farmer for most of it, but spent some time working as a guard, after he was expelled from the militia life he ended up in Dagger Falls, looking for work as an adventurer, or a mercenary as he would call it.
His attempts were failed and he decided to end any type of career, he retired and started hunting deers for food, he grows old, and is near death.
The first memory of life Marana Lanneset had was watching a rat crawl around a cellar. A Cellar in which she spend her childhood and teenage life in. Locked up by the Mad Red Wizard Majar Akala, in his tower near Thay, she was constantly submitted to enchantments, rituals, experiments, and abuses for all she can remember.
One day Marana finally managed to escape, since Majar had already gotten too used to having her always obey, or pretending to obey, as she would think. The woman busted out of the tower and fled as far as she could go, so that Majar would never find her again.
When she established a good understanding of Faerun and its inhabitants, she set a goal for life. She decided to become a professional assassin, so that she could go back and hunt Majar and all of his assistants, and see them beg for misery.
She stumbles around the world looking for anyone to teach her the arts... she is now in Dagger Falls.
