In the end, Fiore still made her position clear regarding Sieg.
"Putting everything else aside, since you have already become Rider's Master, I hope you can lend us your strength."
In other words, Sieg's proposed objective could perhaps be considered to some extent.
That was only natural.
At present, the Black Faction was at a complete disadvantage.
Yet the Holy Grail War was still ongoing.
To oppose the Red Faction, the Black Faction needed Astolfo's combat strength no matter what.
For the Black Faction's current situation, having one more Servant meant having one more card in hand.
Therefore, in order to secure Astolfo's strength, Fiore and the members of the Yggdmillennia clan decided to compromise.
"Since the Homunculi's mana supply is meaningless now anyway, if you agree to lend us your strength, then freeing the Homunculi isn't something we can't discuss."
That was Caules's stance.
And it was an extremely accurate stance.
Having lost Saber (Siegfried), Lancer (Vlad III), and Caster (Avicebron), the Black Faction had almost no Servants left who could make use of the advantage provided by the Homunculi's mana supply.
Rider (Astolfo) had formed a contract with Sieg, and Sieg now fully provided his mana. This Homunculus could not possibly let his Servant drain mana from the companions he wanted to save.
Assassin (Jack the Ripper) had already gone out of control. Her mana problem was entirely solved by devouring souls, so she had never been within the scope of the Homunculi's supply to begin with.
As for Berserker (Minamoto no Yorimitsu), Fang Li had never counted on the Black Faction in the first place. Her mana problem was handled with Mana Ore, and even if the Black Faction intended to provide mana, he would not accept it. Who knew whether they might tamper with it?
