Servalia

Servalia is the femslash ship between Serval Landau and Cocolia Rand from the Honkai: Star Rail fandom.

History
Cocolia and Serval were once close childhood friends. They both attended school together and lived in the same dormitories. In adulthood, they were so close that they didn't differentiate between each other's possessions, sharing everything. One of these was a guitar Cocolia had given Serval, which Serval designed but didn't have the materials to make.

Cocolia eventually became the Supreme Guardian and Serval served under her as a researcher in the Architects. When Cocolia was a teenager, the Stellaron, a malignant and destructive force, spoke to Cocolia, promising to fix Belobog and make her wish come true. Cocolia believed in this voice, allowing the Stellaron to influence her decisions. This would later lead to her falling-out with Serval. Serval discovered that the Stellaron is in the Northern Plains. Knowing the Stellaron's connection to the Fragmentum and the Eternal Freeze, Serval was determined to investigate since it could be key to saving their world. Serval pleads Cocolia to let her bring a research team there, but Cocolia doesn't allow since this type of research is forbidden. Serval exclaims that they can end all of the suffering, asking why Cocolia would hesitate. Cocolia, who had now sided with the Stellaron, replied that Serval needs to come to her senses. She calls the guards to take Serval away and close away her lab because of illegal research, kicking her out of the Architects. Serval asks why Cocolia had grown so cold. Cocolia doesn't answer her question, but tells her that she was her most cherished friend. Serval and Cocolia haven't been on speaking terms since.

Throughout the years after their falling out, Serval was never able to understand how the Cocolia she once knew changed so drastically. Many of the possessions they shared, including the guitar Cocolia gifted to Serval, remained in Cocolia's office. Serval hoped that one day Cocolia would return the guitar and they could make up, though that day never came.

Quote
"We were like sisters once — inseparable. Of course, that was all before she became the supreme guardian..."

- "Cleanse in the Darkness Outside" quest.

"Cocolia... It's been so many years since we last spoke. We were great friends once — there was nothing we wouldn't share. She became a completely different person when she took on the supreme guardianship. The convictions she once held, her enthusiasm... it was like they were drawn out of her by some mysterious force. She gave the order to expel me herself and refused to see me... I never understood that behavior, and I gave up trying to use logic to work it out a long time ago. Sometimes I ever wonder whether she really did become a different person... is that possible? Perhaps there's a single guardian's consciousness that gets handed down from generation to generation... and the real Cocolia has already vanished. Is she being compelled by previous generations of guardians to make such baffling decisions? Who knows... but this might make for good songwriting material."

"Bronya's a good kid — you can tell she learned a lot of Cocolia. *sigh* It's been a while since we saw each other. I miss her."

- Serval, "About Bronya" voiceline.

"The Cocolia I know would sit on the roof and listen to my songs, but... not the supreme guardian."

- Serval, "About Cocolia" voiceline.

"All that time we spent together... was any of it real? It was so easy for you to just leave this world behind... Don't you at least owe me an explanation!?"

- Serval to a Fragmentum Guardian Shadow of Cocolia.

Fanon
Servalia started being shipped since before Honkai: Star Rail‘s release. Fans saw much angst potential due to the two being former friends. This lead to interpretations of them being exes, with many finding their relationship similar to a divorced couple. Some have compared Servalia to Mistandra, another femslash ship that involves one of Bronya's moms.

Servalia peaked as the 5th most popular Honkai: Star Rail ship on AO3. It currently has 13+ works, the same amount as other ships ranking 10th place in the Star Rail tag.
