Hi, so, just finished reading my copy of Fire in the Sky.
I jave a question:
All the cultists (including Tlalli) have the Crazy Condition. Meaning their Mental duels should be reduced by the same amount. This would mean their Willpower final totals are very low (though it doesn't show this in the stats) and Tlalli is essentially a wet lettuce: her main attack is The Light of Creation, a theoretically devestating 3/4/5B attack that causes Blind, only she has an AV of 8T (though the Tome seems mostly cosmetic as she has no triggers, I assume it is a 'well it is a Sorcery spell' sort of thing) and her Obey has an AV of just 11M.
As she's likely to be a final battle in the adventure she's a pretty huge anti-climax!
