Seen in one screen is a “golden knight”, summoned by a player. It’s not clear if this is an NPC or a special phantom, but it’s not a bog-standard co-op session, because that’s also pictured – see the two knights back to back, one of them outlined in white?
Two more multiplayer phantoms are seen – the blue and red raiders. Both seem to be hostile to the host player, and may be the Pyromancer and Gravelord
mentioned in recent coverage.
You can even catch a glimpse of two NPC characters, both working at a forge.
