History
Norse Paganists Riots
Jakob Nystrom and Petra Larsen started a series of riots in Oslo sharing the strength the Berserker Staff retrieved at Trillemarka National Park.
Nystrom, Larsen and a group of about a dozen of their followers destroyed many properties and left at least 20 injured, three in critical condition, proclaiming themselves to be gods in a message spelled out on the streets of Oslo.[1]
NEXUS
- "NEXUS?"
"It's the world internet hub in Oslo. Every byte of data flows through there; fastest access on Earth." - ―Steve Rogers and Bruce Banner[src]
The Avengers learned from Nick Fury that someone was actively preventing Ultron from gaining access to nuclear codes. Tony Stark went to the NEXUS Internet Hub in Oslo to find out who their ally was, who was revealed to be the remnants of J.A.R.V.I.S., with Stark managing to recover the remains.[2]
