Flashback - The X-Men's first battle with the N'Garai, specifically Storm's destruction of the obelisk which was the nexus of the gateway between their world and ours. The X-Men believed that, with the obelisk gone, the gate was sealed, but a lone demon slowly crawled from amidst the rubble, free in our world.
In the present day a couple out looking for their first Christmas tree. Quickly their happiness became ashes - the N'Garai demon killed them swiftly and then feasted upon them, body and soul.
