Short answer:
We don't know.
Long answer:
It could be anything. It might be related somehow to Trell's intent, but considering we don't know Trell's intent, and even if we did, Atium and Lerasium are only tangentially related to Preservation and Ruins intent, with Lerasium giving you power to preserve yourself and others, and Atium making you an efficient killing machine, or giving you the opportunity to ruin your age temporarily in exchange for lowering it later, so we probably couldn't figure it out.
