Seedling

Seedlings are the mutated plants tended to by the Berserkers which grown into World Hearts and are capable of converting Elex into Mana, purifying the surrounding landscape and promoting the growth of nature in the process. During this stage of growth, the Seedlings are fed Mana by the Cultivators who tend them. Because Mana is made from Elex, desperate mutants can sense it and attack the Seedlings to devour what they believe to be Elex. Devouring Mana instead, it weakens them - at the cost of the Seedlings, something which is unacceptable to the Berserkers.
