Karlach

Karlach had dark red skin, that was covered in scars, and black hair that she wore long on the top, and sheared on the sides. Her two black horns resembled those of a ram, though the right horn had broken in half. She is also very tall. She appears to be 6'3

Karlach was an exceptional martial combatant. Due to her time in Avernus, she seemed to possess an encyclopedic knowledge of fiends and how to fight them. Additionally, Zariel had Karlach's heart replaced with an infernal engine, enhancing her physical prowess and causing her body to burn like fire, especially in moments of great passion. This engine could be further enhanced by inserting soul coins. However, the engine was not made to operate outside of the Hells, and threatened to burn Karlach alive if she remained in the material plane for too long.

At some point Karlach lived in Baldur's Gate in Faerûn, where she worked as personal bodyguard for Lord Enver Gortash, however in 1482DR Gortash betrayed her, by selling her to Zariel, the archdevil ruler of Avernus. Karlach was forced to serve as a soldier to fight the blood war for 10 years.

In the Year of Three Ships Sailing, 1492 DR, Karlach witnessed a mind flayer nautiloid pass overhead on the battlefield of the blood war while being chased by the Blade of the Frontiers. She saw the vessel as an opportunity to flee from her position as Zariel's champion, and boarded it as a stowaway. Unfortunately, she like others aboard the ship, was implanted with a mind flayer tadpole, albeit one that did not immediately begin the process of ceremorphosis.

The nautiloid traveled the planes from Avernus to the world of Toril on the Prime Material. It plummeted to the ground in an area of Faerûn known as the Sword Coast, and several of the captive―or in Karlach's case, stowaway―passengers were left alive after the crash. Karlach then became the quarry of Zariel's agents on Faerûn. A band of her followers led by the fallen paladin Anders tracked her down to a tollhouse along the River Chionthar, wounding but not quite killing the Zariel's runaway champion.

An energetic and joyful presence, Karlach had a great passion for life, appreciating it all the more after escaping the Hells. She deeply enjoyed simple, physical pleasures such as food, sex, and the thrill of battle. Karlach seemed to feel emotions strongly, sometimes descending into fits of screaming rage, wailing sorrow, or giggling joy, depending on the circumstances. As such, she had difficulty concealing her feelings, usually coming across as extremely earnest, almost awkwardly so. Still, Karlach was a courageous warrior and fiercely fought for what she believed was right.

Karlach was a citizen of the Lower City of Baldur's Gate before being taken prisoner and forced to fight in the Blood War, the eternal conflict between demons and devils. She was a prisoner and champion of Zariel, Archdevil and ruler of Avernus, the first layer of the Nine Hells. Taking a risky chance on escape, Karlach boarded a hostile Mind Flayer ship when it appeared in the sky of Avernus. Using it, she made her escape from the Hells but was infected with a Mind Flayer Tadpole in the process. Now hunted, Karlach is a fugitive on the run from Zariel's forces, who seeks to have her warrior returned to her, and punished.

Instead of a heart she has a infernal engine. This causes her body to become extremely hot and burns all who touch her or get too close. But this also means that she is unable to shake hands, hug, kiss, or anything that would involve physical contact

Cheerful, energetic, kind, playful. She commonly calls her friends and companions, "Soldier"

She is commonly seen wielding a large battle-axe
