==Quests==

===Paid in Full===
Glover Mallory will ask the Dragonborn to retrieve this note from the body of Esmond Tyne in Castle Karstaag Caverns. Reading the note will allow the reader to make Improved Bonemold Armor at a Forge.
==Notable items==
*Bonemold Formula – Can be found on Esmond Tyne as soon as the player enters the main chasm, to the left on a small shelf of ice.
*Since the Ruins are inhabited largely by Rieklings, the area is a good location to find Riekling Spears, Boar Meat, and Dibella Statues.
*At the top of the Chasm, past the Bristleback Pen, and across a bridge, is a small area guarded by two Rieklings. Towards the back of this area is an unlocked boss chest, and behind that is a skeleton lying next to a leveled shield and mace. At the same end of the above-mentioned bridge, opposite the boss chest, is a path up the rock face that leads to a locked chest and a leveled armor.
==Trivia==
*There is an area at the top of the waterfall in the main antechamber. It is possible to reach there, where a Skeleton with some gold and a chest can be found. The rocks found there have clipping problems and it's possible to fall through the floor, and into the void (falling off a cell typically spawns the user back somewhere inside it, however).
