What does “Vikings” bring to mind?

OK. Since “Vikings” is one of the three central pillars of the setting concept (“Vikings & Mayans & Dinosaurs”), what does “Vikings” bring to mind?

Just using my memory for now (I can do research later if needed to refresh my memory or get more details):

1) Longships voyaging to distant shores. Raiding and trading. Sometimes leading to settlements or conquest.

2) Fjords. Small isolated settlements. Jarls and petty kings. Rival clans. Feuds. Songs & tales of the ancestors.

3) Thor. Odin. Giants. Trolls. Ragnarok. A cyclic sense of time, culminating in the end of the world.

I think this pretty much covers the essentials of Vikings or a Viking-like culture in a fantasy game world.
