Lucifer was one celestial being who fell in love with Seraph, who didn't feel the same way for him.
He blamed the celestial world for his fruitless love and began to despise gods and wished for their undoing. Eventually, Lucifer acted out and rebelled.
Thousands of years later, he became a demon and turned his holy power into the power of darkness.
Queen of the Gods
Hera is the Queen of the Gods and is the wife and sister of Zeus. She was known to be jealous and vengeful towards the many lovers and offsprings of her husband Zeus.
Hera punished Io - one of Zeus's love interests, by putting her in the charge of Argus. Argus had a hundred eyes and kept vigilant watch over her so that Zeus could not come to her aid. She also turned Callisto into a bear because Zeus fell in love with her.
Bringer of Disaster
After humans received the stolen gift of fire from Prometheus, an angry Zeus decides to give humanity a punishing gift to compensate for the boon they had been given. He commands Hephaestus to mold from earth the first woman, a "beautiful evil" whose descendants would torment the human race.
Hermes gives this woman a name: Pandora – "All-gifted" – "because all the Olympians gave her a gift". Zeus gave her a jar containing "burdensome toil and sickness that brings death to men", diseases and "a myriad other pains". Fortunately, Athena put the "hope" into the bottom of the jar. Pandora promptly scattered the contents of her jar once she reached the earthly world, and so the earth and sea are full of evils. Only hope was left within the jar, however, and thus Pandora is called "Bringer of Disaster".
The name Titan actually means "Rebellion". Cronus, the youngest male Titan overthrew his father Uranus and became the new ruler of the heavens.
However, Cronus was told that his children would overthrow him as well, so he ate each and every of them. Rhea, Cronus' sister-wife, did not like the idea of Cronus eating their children, so she saved Zeus, by feeding Cronus a rock instead.
Eventually, Zeus grew older, and released his siblings. In turn, the Titans were overthrown by Cronus' children Zeus, Hades, Poseidon, Hestia, Hera and Demeter, in an event known as the War of the Titans.
God of Sun
"What a sunny day!" said Apollo, opening his eyes lazily. I wonder what it looks like when it rains with thunders and lightning over the land of adventure. "Maybe shall pay Thor a visit." Driving the Chariot, Apollo's back disappears into the sky...
Ix is the first hero who makes use of gunpower units on this land. Ix's house is full of weapons, but the shotgun he's been carrying all day long, or hand cannon to be exact, is his favorite." This is the work of a true genius, and a masterpiece of talent," Ix laughed.
Goddess of Wisdom
Athena was said to have competed against the mortal Arachne in a weaving competition, afterwards transforming Arachne into the first spider. Therefore, she is known as the "Goddess of Wisdom." In fact, she is also the goddess of warfare.
Athena represented the disciplined, strategic side of war, in contrast to her brother Ares, the patron of violence, bloodlust, and slaughter - "the raw force of war".
