About this mod

A lore-friendly, difficult, expansive multi-path dungeon complex with a cool weapon at the end.

Permissions and credits
Long ago in days of old
the deity of time, red and gold
Cast upon nirn his talon bright
where it tore a cleft with it's phenomenal might
All the time forgotten, yet it rests below
The Talon of Akatosh, with His vow.

My first mod, stand-alone, does not require any DLC (downloadable content), but does require SKSE (how to install here). Cleaned with tes5edit.

This mod adds a more lore-friendly type of dungeon with not too many crazy themes going on (the Dragon Cleft is an old dragon stronghold from the Dragon War and is currently used as a multi-lair for dragons). It is a very large non-linear dungeon as in that it has multiple routes that you can follow. This also require you to explore and backtrack sometimes, because there a couple of ways you can end up where you started. The dungeon in itself is rather difficult and will likely take a few reloads before you reach the end (it also gets progressively more difficult). In the end there is a nice little two-handed sword that unleashes dragonfire when you power attack with it.

To get to the entrance you have to find the old nordic barrow on the highlands south of Lost Valley Redoubt. You can get there by a hidden trail up the cliffs near the highest tower of Lost Valley Redoubt where the hagraven is in.
There is no official quest that appears in your log.
