With Tom's virus removed, ARC gained full administrative access to Hogwarts' magical systems.
"We can now rewrite the castle's defense protocols. Would you like to proceed?"
"Yes. Hogwarts should never be this vulnerable again."
Together, Harry and ARC implemented sweeping magical upgrades:
Wards that shift dynamically—responding to magical threats like an immune system.
Sentient defensive enchantments: suits of armor now acted like spell-sensitive golems.
Automated alert systems that reported dark magical anomalies in real time.
A Shadow Lockdown Protocol, triggered by Unforgivable Curses or presence of Horcruxes.
Arcane Eyes—invisible magical drones that patrolled the grounds, tethered to ARC.
And most importantly: the Room of Origin was sealed behind an access spell tied to Harry's magical signature and intent alone.
