Cissy is one of the characters in Senta and the Steel Dragon.  She is easily the most important non-human character.  Her part in the original story arc of Senta and the Steel Dragon was relatively small.  She appeared in book 3 and then her story culminated in book 5.  When I went back and added what became books 0, 2, and 4, her story became much bigger and I think richer.

Here Cissy runs into Saba Colbshallow while both are shopping at the pfennig store.

The bell above the door clanged once again, this time as a lizardman entered. It was carrying a large hatbox tied with a red silk bow. There were quite a few variations from individual to individual among the reptilians. This aborigine had a face of deep forest green that continued down and was punctuated with darker strips just below the shoulder. Saba immediately recognized by the shorter stature, just under six feet, and the lighter belly coloring, a pale green, that this was a female. Only a few seconds later he recognized who the lizardman was.

“Hello Cissy.”

“Hello Sada,” she replied.

“What do you need, lizzie?” asked Delks in a rather snotty tone.

“Dillingdow’s,”

“Huh?”

“She wants Billingbow’s,” translated Saba. “A six pack?”

Cissy nodded.

Delks raised an eyebrow, and then walked to the back of the store once again, returning with yet another wooden carrier containing six bottles of the popular soda water.

“I didn’t know you lot drank this,” he said. “That will be three marks.”

“That should be one mark thirty two P,” said Saba.

“I can charge whatever I want.”

Cissy set three one mark notes on the counter and picked up the six-pack in her clawed fist. She headed back out the front door, pausing just long enough on her way out to hiss “Asshole.”

“If you’re going to start skinning the natives,” said Saba to the proprietor. “You might not want to start with the governor’s own lizzie.”

Walking outside, Saba found Cissy tilting one of the bottles into her long, many-toothed mouth.

“I like to let mine cool down in the ice box.”

“I know. I see you drink. Cold drink not good to lizzies. I get thirsty. I like Dillingdow’s.”

“Did you pick that up for Mrs. Dechantagne?” he asked, indicating the hatbox.

“No. This is Cissy’s hat. You like to see it?”

He nodded. She carefully untied the red silk ribbon and opened the box, withdrawing a broad-brimmed lady’s hat, made of plaid material, decorated with artificial blue and pink roses and a large green feather. Carefully balancing it on her head, Cissy tied it below her chin with a thick strand of blue lace.

“It looks very nice on you,” said Saba.

“I wear it to shrine, like all the fine ladies.”

“You go to shrine regularly?”

“Yes. I Zaeri now. You Kafirite?”

“Yes, that’s right.”

“Kafira die for hoonan souls. I think not for lizzie souls.”

Saba nodded thoughtfully, and then turned to set his two six-packs into the passenger seat of the steam carriage. He didn’t know much about the lizzie religion, or if there was one now that he thought about it. It was not surprising that Mother Linton was not interested in converting the locals to Kafira, but it seemed like someone would want to. He wanted to ask Cissy who had told her about the Zaeri faith, but when he turned back around, she was already gone.
