Climax of Act I is Logan escaping from Clarissa.
Chased by Stalkers and his goggles scraped by a charged arrow. Awakening the earth elemental. He always has a scar from that graze. Think on this: he survived because the arrow grazed the goggles, did not penetrate them, and because there was some strange protection from the soul infusion of Logan's long association with the goggles. The elemental also knows what Logan is thinking because of that soul infusion. Bring this out later to save Logan's life.
Also, Act II is all about the Ergon and Logan's acceptance into the shamanic world. Awakening of his elemental and tons of trials to become a shaman. Make him suffer.
Journey to Ruh'haddad and learning the truth of the coming Apocalypse. Logan learns to Earthwalk and leads a strike force to shut down the Conduit Plant.
Logan watches as his wife is trapped behind the closing containment doors, the Sweep Team's boots pounding on the ground. He flees as the plant shakes itself apart.
