This mod will add two things: a small keep in the Jeral Mountains and an underground city below it.
The keep is a rather small castle, with a blacksmith, general merchant, and a large storage area for the player in the basement (provided one can find the key for it). This was the first mod I ever made, and has been incorporated somewhat into the storyline of the second area.
The underground city is comprised of a small cave settlement and a rather large dungeon area, as well as a vampire den that the player may join (assuming they are a vampire, of course).
There is also a strange religious sect in the settlement that a player may choose to join in lieu of the vampire den (as they will not accept you as a vampire). The creatures in the dungeon are NOT leveled, and they are quite powerful and quite capable of dealing and taking lots of damage.
This dungeon is intended to give higher level players somewhat of a challenge once they have maximized all of their skills and stats. However, many of the enemies have specific weaknesses and/or attack with specific elements, so it is certainly possible to use spells and enchanted equipment to take advantage of this.
There are also a variety of quests available in the underground city, many of which reward the player with powerful and/or unique items (nothing game-breaking, don’t expect any ridiculously powerful weapons).
At the very end of the dungeon lies an extremely powerful boss, and if a player is able to defeat him, they will gain access to some of the secrets of the Ayran Keep and two rather nice enchanted items.
