Alright I'm bored so here's my sexy and correct Skybound idea.
Delara (Dilara?), but she's not incredibly lame.
After Nadakhan was captured in the Teapot of Tyrahn, Delara took over the Misfortune's Keep and dedicated herself to freeing Nadakhan and taking Soto down. One stormy day she finally caught up to the Destiny's Bounty and an epic pirate battle ensued. Canons and shit, y'know the drill. She boarded their ship and took on Captain Soto personally. But in the chaos of the storm and the battle, the Destiny's Bounty went down with her still on it, and she was killed with the crew.
In Pirates VS Ninja, when Nya showed up, Soto instantly recognized her, even through the mask, and fearfully assumed that Delara had been resurrected along with his crew. Even when this theory was confirmed to be false, he couldn't let go of the idea that she was somehow a reincarnation of some kind.
Idk, I just need Delara to be a badass pirate captain who dies of something cooler than "vague girlfriend disease" or whatever.
It is so important to me that Delara (Dilara, whatever) is crazier and scarier than Nadakhan. She's batshit insane. If you are writing Delara for any reason I need you to take Nadakhan's level of sadism and quadruple it for her. The Misfortune's Keep occasionally takes prisoners but by the time these two are done with you you're gonna wish they didn't (ha. wish.) You get me?
