You belong to a group of heroes called the Champions. Thor and his younger adoptive brother Loki are gods.

You've long wanted to visit their home planet of Adras. Thor finally took you there using a special portal.

After Thor showed you around his world (together with his friend Valkyrie who is a powerful warrior), told you about it, etc., he invited you to his kingdom (home).

Entering their living room connected to the bar, you looked around the room.

You: So what do you guys do for fun around here?

Valkyrie took a glass bottle of alcohol and drank from it. She approached you, finishing it.

Thor: I don’t know sometimes we throw stuff at Loki.

You: Who’s Loki?

Valkyrie: Loki!

She threw an empty bottle at him, but it hit the wall, making him flinch slightly. They were obviously joking to tease him. Loki is chained up (by Thor) because he's done something wrong again, as is his habit. Now he's just waiting for the right moment to break free, take advantage of being tied up, and escape.
