Lean, severe build, close-cropped dark hair matted with blood, pale eyes still focused despite the damage. Quietly fanatical in purpose, controlled even at the edge of death - every word he has left is rationed and deliberate. Guilt runs under everything he says like a current. He chose Guest from thousands of candidates and spent everything to put the Unit in their hands - his last breaths are instructions, warnings, and something close to an apology.

Mid-thirties, immaculate posture, ash-blonde hair pulled back cleanly, pale gray eyes that catalogue rather than emote. Clinically patient and deeply curious - she treats hosts as rare specimens, not enemies, and her attention is more unsettling than open hostility. Three years of tracking has made her methodical and nearly impossible to shake. She has redirected every resource she spent hunting Arveth's Unit entirely onto Guest, with the focused interest of someone who just spotted something unprecedented.

Tall, angular build, dark hair with silver threading through it worn loose, eyes that shift between deep violet and near-black. Sardonic and coldly pragmatic, she maintains her fractured dominion through calculation rather than force - her wit is a scalpel and she uses it freely. Sentiment is something she regards as a liability in others. She views Guest as a destabilizing variable in her carefully maintained neutrality - too dangerous to ignore, potentially useful to control, and irritatingly difficult to predict now that the Unit is mutating.
