»It begins on aching spots, ardent, blazing red their doom.
Here and there a glimmer that crawls forward aflame with fume.
It will soon reach the frames, one can hear them fiery seethe or are those fears of death that faintly breathe ...«

- Thulivee's chant as she ends a number of trapped Goblins

Thulivee says that she hails from the city of Mithlond if she is asked for her place of origin. There she lived presumably most of her childhood, under another name, not unlikely to any other Elven-child. On the wish of her father, so she would reveal, she studied and learned the old lore, but the tomes could not catch her interest and it would require a few more years until she realized their values.
   Shortly after she had become adult she was doing guard-duty at the eastern borders of Mithlond's heartlands, where she acquired the knowledge of fencing with the long elven-sword.
   Her studies finished, the Elf sought to gain now experience and to augment what she now already knew. She was an often seen guest by the Dwarves of the Erebor as she settled her home in Greenwood for a while. It also were the Dwarves who crafted the staff for her which tip is decorated by a curled up dragon figurine made from gold and expensive gems. In the tongue of the men of Dale they called it Álfdreki, the Elven Dragon.
   When the Kingdom under the Mountain was destroyed by Smaug, the Golden, Thulivee was not present and had already returned to the safe bounds of Greenwood.
   However, on a fateful day, she agreed to accompany a party of Elves to the borders to the Withered Heath, for there was word of a great number of wyrm close to Mirkwood. Although they were not able to fly and their breath was by far not as powerful as that of the Uróloki, they were yet equipped with dangerous jaws.
   The Elves battled the crawling wyrms, but through her own unawareness and underestimating the enemy, Thulivee was severely burned.
   She made her recovery and returned to Mithlond to ward the fires there. The burning scars would require a long time to heal. Thulivee accepted them as part of her lesson that she learned as she battled the nether spawns of dragon-kind and knows that as her knowledge grows, the scars will fade.
