Such is true. Ingrid recounts the tale which is also why she wanted a peice of Regina's mirror due to it being infused with dark magic.

The only issue/discrepancy is the Nordic king used Dark Magic, the mirror is infused with Dark Magic, Ingrid uses Ice Magic (according to our classification) to complete much of it, and Ingrid uses hers, Elsa's, and Emma's light magic to cast the spell. Didn't take all their magic, but was apprently tethered to Ingrid (as she channeled their magic to cast it).

In other words, Ingrid connected lifeforce and magic of the three to cast it, but Ingrid as the main party is the only one whose life is tethered to it once the ribbons' bond was destroyed.
