Your attempt to clear The Underworld was... successful! Sometimes, destiny does like that sort of thing. They aren't here though; The End is. He finds it a bit gauche personally.

He wields not a bow or gauntlets, but a weapon based off the one taken up by Death: a scythe. Its reach is long and relentless (double meaning not intended, ugh, he hates it here sometimes) as he strikes the pair swiftly. Unfortunately, he miscalculates the advantage that hiding in the shadows of the snow-coated pillars will give him. Artemis' arrows find him and Rosie, too, uses her own heightened senses to force him to fight plainly when possible.

Between both of their bows, Rose and Rosie are able to take down The End. He 'dies' in a fittingly dramatic burst of starlight and scatters to the wind. But as they find their way through the mountain pass and towards Persephone's cottage, a deadly blizzard blows through. It claims them both in an unexpected flash freeze and sees them waking up back at The House of Hades.

Hypnos greets them both: "It says here you died of... hypothermia! Huh, how about that? Maybe I can lend you an extra blanket for next time!"
