Barbara

"Ellooor" - translated into standard English as: 'Hello'
Barbara, also known as Sexy Barbara by Camila, was the innkeeper of 'The Thundering Lizard' within the city of Port Nyanzaru and was regarded as a local community hero and an all-round great person, who served many people. Due to her incredibly strong northern English accent (performed by yours truly Kelloggs) and her apparent loud affection for the party (specifically for Dave), she is regarded as an iconic character. She was introduced during the first session of the Tomb of Annihilation campaign, where she served and helped the group of heroes known as the Comrades and gave them a place to stay. To the party's surprise however, it was revealed during the final session that she was in fact a demon or a doppelgänger of the real woman and turned on the party, specifically Jaffie. It is believed that she was purposely planted there by the lich Acererak to hunt down any adventurers interested or tasked with ending the death curse.
Her most famous moments occurred during the final session of the campaign, in which she lured UwU, with the help of chef Big Man, into the kitchen (where she belonged). This in turn would make the other members of the Comrades suspicious and would follow the kenku back to the Inn, where once there Jaffie was told to go in the kitchen where Big Man was waiting for him. Upon entering Jaffie killed the chef Big Man due to seeing him attacking UwU ("mAke SAndWIcH!"). This however, seemed to be Barbara's plans all along, and so once Jaffie was in the kitchen freeing UwU, Barbara transformed herself into a demonic lord and summoned a mighty Balor, destroying the Inn of 'The Thundering Lizard' in the process. With the Russian Lady also there, she and the Balor would battle it out above the sky of the city, thus enacting the iconic event known as the Destruction of Port Nyanzaru. After the tabaxi Camila shot a bolt towards the demon in the kitchen, this enraged Barbara, so she focused her attention on the tabaxi. After the demon caught up to the tabaxi in an alleyway, Camila fired a bolt, covered in some of the blood she had taken from the cannibal camp, at Barbara. Though this didn't go as Camila had intended as whilst the bolt hit Barbara, her response was "... bro.. brother?!", and with that, she flew into an even bigger rage. As the tabaxi tried to climb a nearby building to its roof, Barbara followed and flew ahead. Once on top, the demon threw her spear at the feline and impaled her to the roof. There Camila knew that she was about to be slain and so in a final plea for mercy, called upon the divine aid of the Lord KB with the quiet chanting of the phrase "WWWHHHHHYYYYYYYYYYY" repeating herself over and over again. Suddenly then, a giant meteor headed straight towards the city, urging Barbara to flee. Once the ash and dust had settled from the great impact, Barbara revealed herself to the rest of the Comrades and challenged them all (aside from Camila whose soul had been taken elsewhere). In the ruins of the port city, the group would battle it out against the demon until the miniature dragonborn Dave slew her with his magical lightning axe.
