Thief Cache

A Thief Cache is a barrel in that can be looted for various items. Thief Caches in Riften appear immediately after the player has joined the Thieves Guild (being the Guild Master is not required). "Special" missions assigned by Delvin Mallory must be completed for each specific hold in order for the other Thief Caches to appear.

The Thief's Cache shadowmark is present on the side of the Barrel.

At higher levels, (tested at level 57) Thief Caches will always contain a Daedric Dagger with a random enchantment, some daedric arrows and gems.
