Frost Heart

Placeholder Overveiw
The frost heart is a gigantic,mystical device on the planet Arctuz.It was apparently created by an ancient sage as a way to extend his & his lover's life.When Frieza's ancestor[possibly Chilled],arrived he killed the sage & his lover for not telling him how to use its abilities,vowing to find out how on his own.

When Glaciera & Tamana arrived on Arctuz,the rebels who'd taken over,in order to overthrow the Cold family's rule managed to capture them & tossed them into it to hold as prisoners,despite their insistance that they hated Frieza as well & were willing to help them.The frost heart then froze then cryogenically.Apparently the rebels were desroyed by Cooler who regreted not keeping one alive because he couldn't  free Glaciera afterwards no matter how much he blasted away at it.

The frost heart resembles Superman's ice fortress except it glows & emits a sound similar to a heartbeat from within;hence the name frost heart.
