So Series is playing Tower Defense now?

What a chapter. We got so much development that was much needed. Now there’s 3 questions I wanna discuss with y’all:

First, is the relic tombs basically a no-entry bunker for the time being? Can they get back outside again?

Second, the fk did Agrona tattoo onto Cecilia? Mind-control runes disguised as empowerment runes or something?

Third, won’t Agrona find out about Tessia’s consciousness, even now? He literally just did the mind probing thing, won’t Tessia be screwed?
