Born the daughter of a human lord and a wood elf she began her life in Cloakwood Forest. From a young age she was educated in the ways of the elves and the ways of the humans. However she was not fully accepted by the humans due to her background and only accepted by the Elves of Cloakwood due to her mother being an elf of high standing among the group. This prevented her from fully associating with either race except for those who earned her trust. And with her, trust was a thing that was as valuable as the things she stole.

A ranger that traded with the various groups of elves that populated Cloakwood Forest taught her the ways of stealth over the years, but she took his teachings a step forward by using them in various thefts and robberies. One night she took her skills to the limit by attempting to steal from a convoy of the Black Talon Elite that was traveling the from from The Friendly Arm Inn to Baldur's Gate. She almost succeeded undetected, but was discovered by the leader of the convoy when she set off a trap while attempting to take off with the prize of the convoy; The Paws of the Cheetah. Apparently the convoy leader was the only one to survive the assassin who was the previous owner of those boots; he shot a poison arrow into the assassin as he was advancing on him. Needless to say, the assassin did not survive the encounter and the convoy leader took the boots as his prize. Unfortunately for Frost, the convoy leader valued those boots and was not prepared to give them up without a fight. Frost was not the best of fighters and lost the duel; but not before mortally wounding the leader. Using the last of her strength, she grabbed the boots and stumbled off into the night with the convoy leader's sword stick through her side.

The convoy's guards pursued Frost and found her a day's journey later, unconscious and dying. They dragged her back to the camp where the convoy stationed themselves while waiting for their guards to return and to the convoy leader; who was still alive, although not in good shape and required a healer urgently. The convoy leader took back the stolen boots and his sword from her side. Then they left her for dead on the side of the trail and continued on their way. Somehow she survived the next three days at the edge of Cloakwood Forest and when she came to, the wound in her side had miraculously healed enough to stop bleeding. She dragged herself back into Cloakwood Forest and to one of the several groups of elves that lived in the forest where she spent the next month recovering from her near death encounter.

To this day Angel learnt a valuable lesson that she has never forgotten; "Always remember to look over your back every now and then; you never know who might be about to stab you in the side..."
