Kade Mahendra was always a temperamental child, but it wasn't until she reached puberty that her family realised the unpredictable weather patterns which had developed in their region were actually caused by Kade's whims. When she was upset, the area around Surabaya was drenched in monsoonal rains, and when she was happy the sun would always shine.

Kade wasn't a particularly happy child, however, so the people of Surabaya were more accustomed to the torrents of rain. Her parents were both scholars, firmly entrenched in the ideology of the State and seemed to pay more attention to their son, Setiawan, who was two years older and never without opinions or words. Kade studied hard in the shadow of her brother and earned a position at the Trisakti University in Jakarta. Setiawan, meanwhile, had become a political activist, voicing his concerns over the West's continued dominance and egotism in relation to Asia. His vehemence was particularly directed against the United States and Australia, who he saw as the primary threats to Indonesia's successful political and economic future. Kade watched her brother become more idealistic, while she became obsessed with science. The siblings grew closer together during these years, and when Setiawan joined a jihad-inspired terrorist group, she followed.

After two years at Trisakti, Kade won a scholarship to Oxford University in England where she graduated with a Doctorate in Meteorological Science. She returned to Indonesia and earned a Master's in International Relations and a position at the University of Jakarta. She had lost contact with Setiawan and forged a career as a well-paid meteorologist.

When the Marauding Tide launched an attack on the Australian Embassy in Jakarta, Kade recognised her brother in news reports but hadn't realised he had begun associating with ubers, especially ubers with such an extreme ideology. While the authorities couldn't find the Marauding Tide, and were reluctant to allow any international agencies assist with the search, Kade had no problem. It was almost as if the government was hiding the terrorists.

And that was exactly what had happened.

Setiawan explained that the current Indonesian government had authorised select individuals in the military to operate as a 'black ops'. Marauding Tide was set up to protect the Islamic faith in Indonesia as well as the nation's interests. They were deployed to East Timor and battled the Southern Knights over many months which resulted in widespread devastation to the struggling country.

Kade was invited to join and she agreed. Indonesia was her home, and her experiences overseas had taught her that Muslims were in danger of persecution. She also saw something within the small band of ubers known as the Marauding Tide. They all shared a genuine faith, and Kade believed that their actions would help to motivate and inspire the millions of Indonesians to rally behind their cause.

She knew it wouldn't eventuate overnight, but her brother's determination was infectious and she had been growing more and more comfortable with the wild energies at her command. She longed to throw away her studious life and embrace the primal energies of the weather.

Bayu has a forceful personality which is reflected in the weather around her. When she is inspired or angry, her powers are incredibly powerful, but when she loses faith or is sedated, her powers quickly vanish. She is an intelligent, but idealistic woman, so that all of her education has only managed to make her more judgemental. The world experiences she has enjoyed has hardened her rather than expanded her mind.

She is a devout Muslim and a scientist, but her religion colours her views more so than science.

“Hear the thunder and know your time of truth is near.”

Bayu is able to manipulate the weather in her immediate vicinity. Some of this power is unconscious and manifests itself in relation to her emotional state, but she is able to fully wield several elements including lightning, temperature changes and monsoonal winds.

Bayu is a devout Muslim and wears a black hajib, black shirt and camouflage combat pants. Apart from her face, her entire body is covered, although her dark brown eyes manage to draw the attention of most - especially when she begins to exert her power over the world. Her eyes flicker with lightning and seem to cloud over when she uses her powers.

Out of her Bayu costume, she wears traditional clothing. When in the company of women, or her family, she has been known to remove the hajib and release her thick braids of dark hair; but Bayu prefers a professional appearance and frowns upon most forms of feminine fashion and custom.
