Gideon's power takes shape as psychic binding, able to stop a being it it's tracks and render them inert. With exertion, he can target a few more individuals, but usually this power is leveraged one-on-one, and he was often sent to assassinate high-value targets in the Recursion War.
Gideon fervently maintains his faith despite the events prior to the arrival of the Returned. Certain tenets of his faith have shifted from the orthodox doctrine the Elder's provided, but one certainty rings in his words: The Elders were a blessing, bringing the people of Truetopia enlightenment and the chance to realize their full potential.
