Chapter 14: The Secret Truth
Soon after the Trocks attacked Barren Sander and kidnapped the Priestess, Emirate sent the El Search Party to Vapor to see what she knows. The El Search Party were all baffled by Vapor's youthful appearance, but she was more interested in capturing a Trock in order to get information from him. With the use of a translation device made by her disciple Grail, the Trock spout attacks against human. After a brief torture session by Vapor to the El Search Party's discomfort, the Trock revealed that they had gotten a hold of new powers. However Vapor was not sure where the Trocks would have gotten such magic to aid them. After the group encounter Waldo, they report to Vapor of the strange device he was wearing, filling him with dark energy. Vapor was disgusted by the revelation and more so that even Harpies were involved in the matter. Suspecting a greater card at play, she tells Emirate to send a message to the Caluso Tribal Village.
With the message sent, she suggests they start tracking the Wind Priestess Anduran, Garpai Rock being her first logical location. When the El Search Party described that Harpy that took Anduran, Vapor recognized the description as being Kelaino, their strongest and arrogant leader. Knowing Kelaino, Vapor was curious why the arrogant Harpy would work alongside the lowly Trocks. Given the word that the Priestess was already taken to another location, Vapor aimed to calm the dispute between the Harpies and humans, in order to get Kelaino's attention, Vapor takes out a Harpy feather. She explains alongside Emirate that due to their high value, Hapries were hunted down and stripped of their feathers, this brought great animosity between he species till a peace agreement was met and the trade of Harpy feathers was deemed illegal in Sander. She hoped that the feather would catch the Hapry leader's attention. And rightfully so, Kelaino came to speak with Vapor or Emirate. Accusing the humans of breaking the peace agreement, Vapor said they had done so such thing. After the conversation, Kelaino stormed off to send her two minions Aello and Okypete to hunt down the messenger they sent to the Caluso Village. Vapor commands the El Search Party to stop the two. Aiming to clear the misunderstanding, Vapor made her way to Kelaino. There, she asks Kelaino why she kidnapped the Wind Priestess and what she had meant by sensing dark energy from the Wind El. Hearing Kelaino, Vapor tells the Harpy that demons had been invading the world as of late. With Elsword explaining the rest, Kelaino realized she had been fooled by the witch Karis. Kelaino told the group that Trocks had taken the Priestess elsewhere.
Chapter 15: The Predicted Misunderstanding
Vapor suspected the Trocks must've taken Anduran to the Trock's Lair. Arriving, the Trocks attacked the El Search Party, Vapor suspects they must be under the control of Karis. Hoping to soothe the situation, Vapor concocts a medicine decided to calm the Trocks down, the awful smelling liquid did help in letting the El Search Party make their way into the lair, however Anduran was nowhere to be seen here either. Needing to find somebody she could make sense of, she storms to find Chieftain Trockta, Elsword tries to tell her that it is too dangerous but Vapor give hims a sharp growl causing Elsword to back off. After successfully breaking Trockta out of his mind control, Trockta tells the group that Karis had taken the Priestess to Parugo Mountain to awaken the Trock's old home. Vapor then pieces together that Karis is really trying to unseal the Behemoth, the Holy Beast sealed away and protected by the Caluso Tribe. Vapor remembers the previous incident where the Behemoth nearly wiped out Sander during The Rage of Behemoth. Inspecting Trockta's amulet, Vapor discovers that it is enchanted with a Dark El spell, the matter they face is not longer a matter of Trocks but a disaster with Demons involved. Needing to keep Behemoth sealed, Vapor needed to get in contact with the Caluso stationed at Parugo Mountain. Elsword informs that they had not received word back from Emirate, concerned, Vapor requires contact with the Caluso's Great Chieftain Karu.
Once at the Caluso Tribal Village, after freeing Emirate, Vapor suspects that Karu is too under the Dark El's spell. Elsword confirmed it with a look at their eyes, Vapor states that the warriors are strong and will try to resist the control, however Chung explains that the control is strong and is not easy to fight against. Returning back with little progress, Vapor had grossly underestimated the Demon Spell. Vapor hypothesizes that if they could overload the Wind El, its power could push out the Dark El's influence over the Caluso. She tells the El Search Party to collect Wind Spirits from the Sylphids while she worked on the enhancer. With the setup ready, she give it to Emirate and wishes the young chief luck.
Chapter 16: Soul of the Wind
Solving the problem with the Caluso, Vapor is still gravely worried about the matter of the Behemoth. She says that it being released is bad enough, but being under the Demon's control is a catastrophe even greater. Soon, Vegar arrives and interrupted with bad new. Vapor was horrified that Behemoth had been unsealed. To help in the efforts to stop Behemoth, Vapor agreed to help repair the ancient Caluso airship, the Sandtilus. She explains that the ship will help them restrict Behemoth's mobility and with the help of the Caluso Wind Shamans, they might be able to stop the Holy Beast. During the battle, Vapor helped control the ship's weapons. After immobilizing the Holy Beast, Vapor begs the El Search Party to rescue the Wind Priestess.
After the El Search Party defeated Karis once and for all. Vapor was in utter awe as the El Search Party had saved all of Sander from certain doom. However the celebrations were short lives, Anduran's visions saw a powerful Demon beyond any other, Vapor expresses her concern, Anduran tells the El Search Party they must find the other Priestesses.
