Duel at the Elven Royal Castle

Assassination Attempt on Mare Bello Fiore was a battle between one of the Sorcerer Kingdom's 6th Floor Guardians, Mare Bello Fiore, and the Extra Seat of the Slane Theocracy's Black Scripture, Antilene Heran Fouche. It would end up being the spark that led to war between the two nations.

Background
Whilst on a covert mission in the Elf Country with the 6th Floor Guardians, Aura and Mare, to get it's Dark Elf population to migrate to the Sorcerer Kingdom, Sorcerer King Ainz learned that the Slane Theocracy would soon be attacking the Elven Capital. Not wanting the treasures within to just fall into enemy hands, he infiltrated the city alongside the twins with the intent to loot the treasury. However, this led them to cross paths with Elf King Decem, who assumed the Floor Guardians to be his grandchildren and ordered them to bear his offspring. This enraged the Sorcerer King and a battle ensued which ended in Ainz's victory. However, the Elf King managed to escape, prompting Ainz, who wanted his equipment, to send Mare after him while he and Aura looted the treasury.

Meanwhile, the Theocracy launched a full-scale assault on the Elven Capital, intending to finally end their long-term war with the Elf Country. As part of this offensive, the Theocracy sent Antilene Heran Fouche to assassinate the Elf King. Intercepting him in his throne room as he attempted to flee the country following his loss to Ainz, the Elf King assumed her to be Aura and Mare's mother. However, Antilene had no idea what he was talking about and proceeded to kill the already exhausted monarch with ease.

Right after Antilene completed her mission, however, Mare entered the throne room. Assuming him to be one of the grandchildren who the Elf King mentioned earlier (and a girl due to his cross-dressing), she attempted to kill him by throwing the monarch's corpse at him. However, Mare dodged it, surprising her. Striking up a conversation, Antilene is shocked when Mare introduced himself as being from the Sorcerer Kingdom, recalling the "Thousand Leagues Astrologer's" report on the Dark Elf who accompanied the Sorcerer King during the Massacre at Katze Plains.

Antilene continued to question Mare, but all she got were some stuttering replies that did not reveal anything aside from that he was not alone. Concluding that she will not get any information from this conversation and now knowing that he had allies, she decided to just subdue and kidnap him so she can properly interrogate him later.

Battle
Closing the distance between them instantly, Antilene swings her scythe at Mare's legs. However, despite being caught off-guard, he blocked it with his staff. Although surprised at being countered so easily, Antilene continues swinging her scythe as a confused Mare repeatedly deflects her strikes whilst stumbling back to try to create some distance between them. Considering her opponent's strength, and the fact he has allies likely on par with him, Antilene concludes that she will have to settle this quickly and gives up on adducting Mare in favor of just killing him and taking his corpse to be [Resurrected] later.

Antilene failing to kill Mare through her surprise attack meant that the fight would not become a battle of attrition. Having concluded Mare to be a fighting type, Antilene is shocked when he buffs himself with the spells [Power of Gaia] and [Elemental Form - Earth]. Having no idea what class those spells fall under, she uses the Inquisitor skills [Denounce Heretic] and [Sentence Heretic], which increases MP costs and spell failure rates for Priests that believe another god than her.

Taking the offensive, Mare rushes at his opponent at incredible speed and swings his staff at her. Despite the attack being rather straightforward, Antilene chooses to block it with her scythe rather than dodge to feel the extent of the buffs. However, the strike was so strong that she was shoved to the ground whilst and forced to use all of her strength just to push the staff away. With Mare now right open, Antilene swung her scythe at the unarmored portion of his armor, the belly, with the Martial Arts [Greater Wind Stride], [Steeled Arm Strike], [Greater Piercing], [Greater Ability Boost], and [Greater Possibility Sense], managing to injure him. Before she could pierce his organs, however, Mare uses the skill [Instant Counter] to knock Antilene away.

Using the Martial Arts [Pain Suppression] and [Greater Wind Stride], Antilene regains her footing and uses her strongest healing magic [Greater Recover] to apply first aid to herself. Mare, meanwhile, uses a scroll containing the 6th-tier spell [Heal] to heal the wound Antilene just inflicted on him. Watching what little she managed to achieve being undone, Antilene considered using one of her two trump cards. However, she ultimately did not wish to resort to that jet.

With her Martial Arts still active, Antilene once again attacks Mare with her scythe, this time aiming for his wrist. However, he just tanks the hit with his right arm before swinging his staff at his opponent with her left. Unable to avoid the attack with Mare holding her in place, Antilene resorts to enduring the hit using the Martial Art [Greater Reinforce Defense]. Still, she could not completely avoid taking damage. From this exchange, Antilene finales Mare's strategy: tank her hits and counter with his own whilst healing off any damage he receives.
