This may have been answered along time ago, but how did Laknaat bring Gremio back? I know her she used her rune and the 108 stars as a "power source" if you will, but what was her mechanism, did she remake a body and get his soul back from Souleater? Or did she pull him from the past right before the spores ate him? (it sounds crazy, but given gremio's comments the second he materializes it could be possible)...IDK ..how did she do it, because even if one brings gremio back to life, he is still one of the 4 souls that attacks Windy at the end when she tries to take the rune.
I will establish one mighty nation in this land... a single, powerful nation, born of force and wielding force... that's the one and only way of freeing this land from war.
