Spoilers? For a mod quest anyways.
Skyrim! I've been playing again recently, I tend to go through a round of playing sometime every year. I usually have three different characters I play, but the only one I've been running recently is my Argonian (battle?)mage Kyra. Downloaded a number of mods, and I started her off in Solitude as a relic hunter for a recently opened museum.
It's kind of empty right now... scratch that, VERY empty, but right away the curator sends you off to a few places to find items for the museum. The very first place he wanted me to go was Helgen, where someone had written him about a collection of urns they had that they were willing to donate to a museum. Unfortunately it looked as if Helgen had been destroyed by a dragon that I got the pleasure of seeing as I approached the town.
This is pretty much the start to the main quest and you can go warn Riverwood and Whiterun from there, but I was rather sour that all the urns were destroyed, so I ventured to another dungeon to try and find SOME relics to make my journey worthwhile.
Halldir's cairn it was. The dungeon was frighteningly difficult at a low level, but going through it ended up being worthwhile. I got quite a few items for my collection - a full set of Ancient nordic armor, a number of gemstones, and best of all a unique staff that I got to display in the main room! A trip back to the museum to place all these items, and then I decided to explore it in earnest.
Above the museum is a place where you can live, and it comes complete with everything you might need. My favorite was the gigantic enchanting table that I wasted no time in using. My previous journey had also left me with a few items of magical nature that I really wanted to learn the enchantments for.
Around the museum I also found a LOT of little secrets. Through them I ended up finding a few more items for the collection, as well as a whole underground room that I could place even MORE items. All in all, I think there's over some 2000 items you can find for the museum, and it ends up adding even more displays if you add other certain mods such as Unique Loot. The museum mod itself also adds numerous items like paintings, decks of cards, and lore items from previous Elder Scrolls games that can either be found or donated by NPCs that visit your museum.
It's an amazing mod, though a rather large one. If anyone wants to check it out, it's called Legacy of the Dragonborn. A word of caution, it's best to start this on a new character. Some quest items can go into the museum, but also need to be turned in for the quest. It's possible to create replicas of these items once you've held them in your inventory, but you can only do that if you had the quest item while the mod was installed.
