The Lost Child

It started with whispers, then blue auras of the gates between worlds began to call out.
The world's inhabitants, bewildered at the Yggadeik's foreign pleads, begin to bring the Tree of Life offerings. Each group brings something different in hopes of soothing the cries.
The Gia - a proud race of man, known for their bravery and policing the world to ensure the safety of others. They placed the finest swords, standing tip-deep into the earth around the base of the ginormous tree. Declaring their service to the survival of the tree at all costs, their swords went for miles - ready for battle should they be needed.
The Furita - a cat-like species devoted to the healing and magical arts traveled up the spiraled trunk into the branches of the tree. It took them several weeks to make the journey on foot. When they reached the highest branches, they hung lanterns that they filled with pink glowing magic to strengthen the tree, heal any wounds, and provide safety for those who might travel there. 
The Tudome - the wise elementals, tall in their humanoid bodies, brought stones that the portals feed on to the openings of each portal. It was a young mother with her infant strapped to her chest; she heard the pleads to grow louder as she moved closer to the gateway, the bright blue glow growing. She hesitated and backed up, feeling the pull on her body. The leader of the group waved her forward, impatient to finish the ritual. The woman, scared, moved carefully with a large yellow crystal in both of her hands. She leaned down to place it at the base of the gate when she heard the screams from behind her. The blue glow absorbed her, and she felt weightlessness as the infant began crying. Her hands slid over where the baby had laid cradled to her chest before she realized that the little girl was gone. 
It all faded in an instant, and the young mother was left kneeling in front of the tree's gate as she sobbed. The child is gone, perhaps sacrificed to the unknown energy that powered the world. Her people gathered around her, speaking of how the tree was silent now and that she should be proud, carried her home among the hills of roots at the base of the life-giving tree.
