Heidi is a cruel and arrogant person, willing to go to any lengths to achieve her goal, even if it means killing innocents or even her own allies.
Heidi wishes to rule all witches but is unable to overcome Tilly's influence and leadership. In particular, the building of the Sleeping Spell gave Tilly a chance to manage all the other witches. Although some combat witches agree with Lady Heidi secretly, most of them don't want to confront Ashes.
Power of Pulverizing (Implosion Inducement) - Heidi can cause fatal damages to anything hollow, whether they were living things or vessels, within 10 steps from the inside by making them collapse inwards. This kind of collapse won't be affected by any other factors, as no matter what kind of vessels Heidi used her power to affect, they would collapse. A wooden one would be crushed, while a metal one would be squashed. For living being, their abdominal cavity and thoracic cavity, would also collapse and squeeze the soft inner organs out.
