Reasons Behind Irene's Help

There was a saying in the federation:

The stronger you grow, the more malleable the law becomes.

Low Awakeners need to abide by all rules.

Mid Awakeners can get some concessions for minor errors.

High Awakeners would be pardoned even for major errors, as long as they could show enough merit.

But when you become a Sovereign.

You are the law.

There were no laws dictating what a Sovereign should or shouldn't do. No person or organization wanted to instruct a Sovereign.

This was defined by historians as the consequence of a strength-based hierarchical society where a single person's worth could disproportionally differ from the rest.

Compared to Old Earth where rulers could be impeached, either through lawful procedures or violent revolutions, Sovereigns were untouchable.

Not because they couldn't be killed, but because they were the pillars upholding humanity against abyssals.
