Dwarf Fortress

Lifted from an old comment of mine:

Also, this was one of the most forlorn pocket worlds I'd ever played through.

The fortress of dwarves I had previously made, succumbed to a necromancer and I had to kill each and every one of them with my adventurer.

He was but a lowly human peasant (with legendary skills), accompanied by a human goddess who rode on the back of a giant hunting cave swallow. She was struck down early on in the game by one of my very own zombified dwarves.

I tried to resurrect her using every cheat I knew, but nothing worked. Angry at the world, I set off alone into the savagery and killed each zombified creature I saw, ignoring the irony of having to frequently resurrect myself in order to do so.

In one skirmish I was completely overwhelmed by goblins, and to my surprise the long forgotten cave swallow belonging to my beloved goddess swooped out of nowhere and tried to help me, but ultimately succumbed to their savagery, though buying me enough time to flee. Even in death, she continued to watch over me.

I craved social interaction, and roamed the world looking for any site that had friendly inhabitants, but discovering only ruin after ruin, leaving me to wander solo through forest retreats, lairs, and fortresses, in a very melancholy fashion.

After a while, I had finally explored the entire map and decided to head back to where I started. I went back to the bloodied battlefield where my companion goddess was overwhelmed all those moons ago, and gathered her remains into my backpack. Together we headed upstream into the mountains, following the river all the way up.

There I buried her atop a mountain meadow, where keas bounded freely. I placed a little wooden statue as a burial marker next to her site, and then built a little house next to it. I furnished it with a bed, a table, a few cabinets and an armor rack. I hung up my weapons and stored away all my other worldly possessions, and finally - feeling at peace with the world - laid in my bed and willingly gave into starvation.
