Undaunted Porter ScampEdit
- "Ah, yes, the Undaunted. That they have decided to train scamps to wear a pack is, shall we say, a prodigious undertaking. I look forward to seeing how much gear goes missing."—Warlock Aldaale

Unstable MorpholithEdit
- "The instability inherent in the structure of some morpholiths makes them unsuitable for use as sigil stones, yet that doesn't stop certain Daedric Princes from trying. Imagine the surprise when said portals don't work."—Warlock Aldaale
The Unstable Morpholith is a glowing orb that can be obtained as a pet by purchasing three fragments from the Impresario for 5 
each during events in 2021. For more information, see the full page. Its default name is "Glimmerstone".
