Constructed
An aeon wyrd is a construct through and through, mended only by repair work and destroyed outright once it runs out of Hit Points.
Your aeon wyrd is immune to bleed, death effects, disease, doomed, drained, fatigued, healing, necromancy, nonlethal attacks, paralyzed, poison, sickened, and unconscious. It can recover Hit Points only via the Repair action and other methods that fix items, not from any form of Hit Point healing. It's destroyed at 0 HP.
