How could Munin have escaped after so much time in captivity?

This is an embarrassment.

Munin was expelled from Pandaemonium for his heretical belief that a Daeva could change the course of the future.

It seems his aim is to prove us wrong afterall. He must fail.

I don't know how he managed to escape a prison that suppresses his power.

Find Munin and bring him to justice.

"If it must be done."
