Okay.. I just have to ask this! Anyone else actually had fun swimming in lava for the first time in Skyrim?

Me and Derkeethus did! (Derkeethus was immune to the lava so he didn't got hurt.. I had to use a shout)

Name of the quest that involves lava in Dawnguard?

The one about the Aetherium. At the very ending, there is lava.

"Lost to the Ages" is the quest name you're referencing. lol

And behind the Aetherium Forge, there's a descent sized lava pool to help ease the stress of your day.

Awwwww...gotta love a good lave bath.

It helps slough off those annoying layers of dead skin. Lets you shine with your true inner beauty...
