"When something ripped a hole in time and space, flavored with a hint of death, shards of the machinations responsible for it fell into the distortion. One shard did land on earth, and Tony nicked it from a friend's lab. The event that followed led someone to him, god or devil, possibly both, who found the mad inventor half-dead in a cave tearing palladium out of missiles. The god or devil, Loki of Asgard, eventually offered him a deal. From there temptation, damnation, and lack of any care for redemption, began to weave tangled webs around both parties, complicating matters considerably."

"Tony's boyfriend disappears for over a year, and comes back with a crazed look in his eyes and some nasty new friends. And Tony's the only one who realizes he might need help."

"Tony and Loki met before the events of Avengers. Could their long-time friendship and love last through an invasion?"
The last one is by far my favorite- hope you enjoy!!
