For me it's the Garden of Flowers with the Jottuns, Bergrisi and Skadi's Gate of Skye. Curiously, it's the only free quest you can see these two giant types together too.

The rainbow I think is supposed to represent Napoleon, although it could possibly be an effect from Skadi's Noble Phantasm too. I was also thinking about how much Skadi's Gate of Skye resembles, if it wasn't made with such ambiguity in mind, Asgard/Valhalla and the Bifrost invoking rainbow there. Skadi's Gate of Skye is a different execution of the original Noble Phantasm, which she believes manifests as a gift of the gods through the shadow castle or fortress associated with Scathach, so there could really be elements to the Norse lair of the gods in its presentation.
