There were two more Breath variants that stood out to the Collector. These were abilities that the Collector classified as 'top-class', indicating that they were developed by Jotnar that were uniquely powerful among their kind and had the necessary individual traits to hone a Breath into a usable form.
The Origin Rune was essentially a 'matrix' by which the genetic expression of a vast number of Jotnar Breaths was stored. The total number of stored Breaths totaled seven hundred and sixty six (766), indicating that the Rune was essentially like a last minute genetic depository that the remaining one thousand or so Jotnar contributed to directly before engaging in their hibernation.
