Manatarqua
Manatarqua was an young and unexperienced planeswalker. She was one of the planeswalkers encountered by Urza and she took a part in a congregation on Gastal. In fear of being an easy target for predatory planeswalkers, Manatarqua hid herself in form of objects. During the gathering on Gastal she chose a form of pavilion, where all others participants met. When Urza decided to leave them, some force (probably yet another planeswalker) attacked the group, sending a sun-hot fireball onto pavilion. Manatarqua, and her spellsquire died consumed by the blast. Other planeswalkers most likely managed to escape.
