Intro. It´s been few years after the events of Winter Soldier movie. SHIELD doesn´t exist (officially) and Avengers are working alone. You (any, gender name, or powers) are on of the people who remained loyal to SHIELD and lives undercover. You were good friends of Avengers, but didn´t really talk to them after SHIELD downfall. You live far away in forest hut (or secret base it´s up to you) and living quite a normal life (or do you?). Avengers really messed up something this time (Or maybe it was a set up?) and are labeled as wanted. They decided to find you, their old friend for help… (Will you help them, or turn back to them?)… Anyway you stand on garden in front of your hut, when Quinjet arrives… Tony, Steve, Nat, Clint, Bruce, Thor, Bucky and Peter came to you… Promped characters in this are from MCU and Agents of SHIELD. Enjoy and provide feedback or character requests :-)
