I'm in a rush and feeling uncreative so I'm going to toss the :turtle: up for someone else
I guess I'll catch my own toss since no one else has:
Name three ways that the player can get stunted magicka (no regeneration of magicka)

Being born under the Atronach, Wielding the Fork of Horripilation and contacting Astral Vapors

What interesting structure can you find in Sideways Cave? And what is the zone name?

I thought the interesting structure in Sideways Cave was the ancient hidden Door. This then leads through to two added zones forming an interesting story line. Sideways Cave - Hidden Lake (a large subterranean lake and waterfall), and Sideways Cave - Lost Abagarlas (the ruins of an ancient Ayleid city, Abagarlas).

I was looking for Lost Abagarlas, which gets you the :turtle: and the lake gets you the :icecream:

Woo Hoo another turtle, but you know what this means though.

According to the label, how long has Cyrodillic Brandy been aged?

In Vanilla Cyrodillic Brandy is just a pink bottle like every other potion, it does not have a label. I am using a mod based off of OOO, so I will answer ten years.
EDIT 5-27 If I get a turtle, it is community proprerty. I will be away from internet access for a week.
