Spoiler for Tir Na Fal:

However in order to summon something, one must have connections to Tir Na Fal. I believe Ganelon's miscalculation is Tir Na Fal descend to Silesia instead of Boroszlo Plains where she was using Titta as a medium to summon her. Knowing that Titta has strong spiritual strength and most likely above all Vanadises, she will be most likely selected as the medium to perform the ritual itself.

@DragonOsman About that... She didn't believe it because she is bonded to her mercenary codes.

Spoiler for Figneria:

Fine will always assume Tigre and others are plotting to make her confused but i believe she will be convinced when she encounter Ganelon for this. All she need is a direct experience and she will believe on how Tigre and the Vanadis will shift their focuses from battling her to defeat the demons since her threat is a very little itself compared to demons.
