— Darnic Prestone Yggdmillennia.
Darnic Preston Yggdmillennia (ダーニック・プレストーン・ユグドミレニア, Dānikku Puresutōn Yugudomirenia?) is the master of Lancer of Black in the Great Holy Grail War of Fate/Apocrypha. He is the one who plundered the Holy Grail from the Third Holy Grail War of Fuyuki.
Although he is over a century old, he looks like a man in his late twenties, not showing a single wrinkle. It seems as if time has stopped for him since the stealing the Grail.
Darnic is the elder of Yggdmillennia who has lived for over a century. Having joined the Mage's Association like the rest of the clan, he attained the highest rank of Grand. Seventy years ago, he participated in Fuyuki's Third Holy Grail War in an unknown capacity, aiding the Nazis to supposedly help them further their own goals. He found the location of the Greater Grail, and with the power of the Nazi army behind him, plundered it. He betrayed the Nazis as it was being transported to Germany without their knowledge, leading to the only details being known that the Grail disappeared without a trace and the magus aiding them also vanished.
He worked hard over time to prepare the Greater Grail for his clan's own use, putting all events in order while discreetly avoiding any suspicion. He did let out information regarding the basis of the ritual to spread. which caused imitation rituals to spread throughout the world. He regarded that as his only misstep, and he managed to avoid detection for seventy years. Known as the Eight-Forked Tongue (, ?), he was a second-class instructor in elemental conversion in the Association of whose students displayed unfavorable opinions.
His true strength did not lie in education, but rather his political skills. Known as a first rate swindler, he worked hard to keep his clan from falling into trouble. Although deceit is common within the Association, he was known for utilize his extraordinary political skills to manipulate and cheat both those who trusted him and even those who did not, betraying and double-crossing all in his path. Three months before the Holy Grail War, he revealed his plans, seceding from the Association to form their own group based around their family.
While leading them, he summoned Lancer of Black two months ago due to his unparallelled strength within Romania, pledging loyalty to his Servant rather than commanding him. They intercepted a force from the Association, but one managed to start the reserve system on the Greater Grail, allowing for a team of Servants to oppose them. He did not worry much, as, while it had been unforeseen, he was prepared for such an eventuality when facing the Association. Out of all those within the clan, he acknowledges Fiore Forvedge Yggdmillennia, believing in her potential to be the future elder.
Although Fiore is able to pleasantly converse with her "grandfather", she holds a deep fear of angering him. Those who defy him are thrown out of the clan's network, left with nothing but a life of misfortune. He has little care for most others in the clan, and he even plans to use Caules as nothing more than a pawn to strike at the enemy.
Even though Darnic may be part of a world that impassively goes against all ethics, he believes Lancer deserves his utmost respect for having been the sovereign ruler of Romania. He treats Lancer as the Lord of Yggdmillennia, deferring to him despite being the mastermind behind the Holy Grail War. He appreciates Lancer's tenacity and zeal towards obtaining his wish, making it one of the reasons that he likes Lancer. He does have some worries about Lancer's obstinate nature, but believes working towards the same goal of completing the ritual will allow them to proceed together smoothly.
Darnic ruminates while looking upon the plundered Greater Grail before the multiple summoning ritual to bring forth the remaining four Servants. The culmination of over sixty years of work has come to fruition, and he is filled with a thousand emotions over it. He is pleased with finally having the means to light the beacon of rebellion against the Association, and he is fine even with the unexpected Red Faction of Servants. He is confident in Lancer's strength and that of his subordinates.
He meets with Fiore, and shows her the bottom of the grail specifically due to her role as his successor. They proceed to the summoning ritual, and he defers to his Lord to oversee it. After its completion, he allows Gordes to keep the name of Saber of Black secret, already knowing of the identity and considering his request to be valid. As the rest of the Master and Servant pairs begin to leave, he thinks about how he does not expect much out of Caules or Berserker, a pair consisting of a lackluster magus and a Heroic Spirit without much mystery, planning to use them for the sole purpose of a distraction to strike at the enemy.
He discusses the state of affairs with Lancer once they are alone, and he is chided by Lancer for being excessively flattering towards him. He reminds Darnic that he is still a Servant even if Darnic does refer to him as lord. As they discuss Lancer's past and his new soldiers, he tells the situation with Assassin and her expected arrival. He later goes to discuss materials to be delivered to Caster for the construction of his golems, noting that such a large quantity is hard without a direct route through the Association. Caster relays the progress of his Noble Phantasm, Golem Keter Malkuth, and Darnic takes his leave.
Darnic possesses the Magic Crest of the Yggdmillennia clan. He is very knowledgeable, allowing him to have understood and reproduced Fuyuki's system that not even many of the first-class instructors of the Clock Tower could manage. He is considered to be a monster who has maintained the fleshly vigor of a man in his thirties despite having lived for over a hundred years
