I don't know where I'm going with this, but I wanted to try my hand at sci-fi/horror and came up with the idea of Eywa having enough and blessing Spider with the ability to turn humans into living plants or trees so that their bodies will restore what was destroyed by their bombs and fire. Spider keeps his power secret so that he'll have an easier time fulfilling Eywa's will without disruption or judgment. So far, he's doing a damn good job and with each successful death, grows stronger.
Here's just a teeny piece of what I have so far.
The first body wasn’t the worst.
Jake had seen enough death to be numb to it. But the more they found, the more that numbness cracked, replaced by something he'd forgotten.
Fear.
One soldier was still standing, his posture too rigid, too unnatural. His skin had gone pale, his veins blackened with something that pulsed beneath the surface like twisting roots. Thin green tendrils had erupted from his fingertips, curling toward the sunlight as if reaching for something unseen. His mouth was open in a frozen scream, but no sound would ever escape. His eyes, once human, had been overtaken by blooming petals as if the forest itself had bloomed through him.
Another body lay sprawled nearby, its flesh cracked open. Vines coiled through its ribcage, wrapping around the exposed bone, flowers sprouting where there should have been blood. A grotesque, living sculpture.
A warning.
Neytiri covered her mouth, her ears pinned back in horror. “This is not the work of Eywa,” she whispered, voice shaking.
