When Thea was still a very young and naive elf, fate played a cruel trick on her. This often happens to those who believe that the Light contains only the True Good, and thus allow themselves to be deceived.

Thea joined the Cult of Solaris, which draws its power from worshiping the Light Titans, hoping to bring good to the world and help those in need. Impressionable like all young people are, Thea fully devoted herself to her studies with the Cult and failed to notice that she gradually became a fanatic.

Like all fanatics, driven by high ideals and the desire to change the world, the young elf let cruelty and destruction enter into her life. In the name of the Light, the Cult committed numerous dark deeds. The pivotal moment for Thea was when they attacked a small settlement of vampires who followed the Cult of the Night.

On that bright day, in the glorious summer sunshine, the earth was soaked with the blood of their enemies. Thea felt herself to be the very sword of the righteous Light, striking fatal blows left and right without stopping for even a moment to think about what she was doing. It was only once her squad had finished their violent purge that the young elf's eyes were finally opened. There, trampled into the ground in front of her and spattered with blood and dirt, Thea saw an amulet holding a blood-red stone. All around her lay the bodies of innocent villagers, their mangled limbs jutting out at unnatural angles. Smoldering embers, blood, and a deathly silence...

The elf could not come to terms with what she had become while serving the Cult of Solaris. Something inside Thea broke, as if a clock had lost a crucial cogwheel, stopping time forever. Perhaps that cogwheel was her naivety — or perhaps it was her pride.

Thea fled straight from the clearing, followed by the bewildered looks and shouts of her former friends. She was running from the Cult, from death, from shame, and from herself. She ran and ran, paying no attention to where her feet were taking her, until she ended up in an unfamiliar forest. It was at that moment that the Beast found her.

The predator's awful eyes seemed to burn into Thea's soul, and she felt her heart tighten. The elf started to run again with all her might, with the furious howling and thumping steps of the Beast at her heels. Thea knew that if the Beast caught her, her life would be over, and she would never get the chance to redeem her sins.

Branches whipped at the elf's face while her feet fell into holes and got entangled in centuries-old moss. Climbing up a hill, Thea lost her balance, stumbled and fell head over heels into a ravine. The Beast slowed its pace and began to descend, seeing that its prey could not escape now.

Having landed unharmed at the bottom of the ravine, Thea jumped to her feet and was starting to look for a way out when she suddenly saw a wounded fawn lying nearby. Looking into the animal's eyes, she saw pain and an imploring cry for help. In that moment, she understood that she couldn't run away anymore: she had to protect the weak from danger. This was her chance to somehow redeem herself.

A sudden peace came over Thea's soul, as she turned to face the Beast and defeat the forces of evil — in the world and in herself. The battle was grueling, but Thea managed to come out victorious. As her lifeless enemy slumped heavily onto the grass, Thea, wounded and exhausted, fell next to him.

The elf's mind was about to drift into oblivion when she saw the wounded fawn suddenly transform into a beautiful woman, whose name was Ingrid — the Empress of the Old Grove. It turned out that this whole escapade with the Beast, and the choice between "saving" or "running away", had all been a test. Thea had passed, proving herself to be worthy. Ingrid healed Thea's wounds and, sensing within the girl the power of the Light and the desire to do good, invited her to become the Keeper of the Old Grove.

Thea had always dreamed of protecting, healing and taking care of this world, and besides, she was devastated and broken. Feeling the need to atone for her sins and find forgiveness, the elf eagerly took the Keeper's vow and plunged into training.

With Ingrid's help, Thea learned to harness the destructive power of "White" light and transform it into healing "Green" light.

During her training, Thea fell in love with Kai, who was excavating the ruins of the orcish Santar and helped to guard the Grove. This young elf came from a humble family, but he was nevertheless a rather narcissistic individual. On one occasion, he almost died while pursuing his own goals; only Thea could save him, risking her life in the process. From then on, their relationship grew stronger, but the overconfident Kai still frequently made mistakes, and Thea, still burdened by her guilt, tried to rectify them.

Once Thea had completed her training and fully mastered her new powers, she realized that in order to overcome the demons of guilt that tormented her soul, it was not enough to remain the Grove Keeper. The girl joined the order of the Guardians to protect the Dominion and stop the senseless bloodshed.
