McDonell Trambellio Elrond (マグダネル・トランベリオ・エルロンド, Makudaneru Toranberio Erurondo?) is the head of the Trambelio magus family, Lord of the Department of General Fundamentals of the Clock Tower, and leader of the Democratic Faction of the Clock Tower in Lord El-Melloi II Case Files.
Born into the Lord and Great Noble Trambelio family, McDonell has grown up with maturity beyond his years as the next expected Head. He is also a powerful politician due to his life association with the Trambellio family.
McDonell is currently with his sixth wife and has thirteen (natural and adopted) daughters, presumably from his current and previous wives.
McDonell possesses a trained, muscular giant body and short blonde hair with a goatee. Due to his advanced age and stressful working environment, McDonell has deep wrinkles on his face, however, his body does not portray his elderly side.
In contrast to Barthomeloi family members, McDonell is a relative pacifist and more willing to acknowledge a person's accomplishments, whether they by ally or enemy. He is a believer of individual potential and hardwork. He is also a daughter-con and a respected family man, accepting his wives' divorces freely.
His fashion sense is closer to Bazett Fraga McRemitz.
The Case Files of Lord El-Melloi II
case. Grand Resolution
He is the one who called for the Grand Resolution, intending to make a proposal to redevelop the Spiritual Tomb of Albion, and in the process reorganize the distribution of harvested materials. The Aristocratic faction is opposing him on this, preferring a more conservative approach. At the meeting, Lord Trambellio produces one of Heartless' apprentices, who turns out to have been his daughter, Asheara Mystras.
McDonell possesses extraordinary Od recovery, which enables him to rapidly and repeatedly use spells of the highest classes of offensive magecraft for up to an hour before needing to stop. Due to this, McDonell possesses a superhuman trained body to support the load, for superhuman close combat and for future combat situations when he is over the time limit.
