Everybody who reaches legendary in a skill I rename after one of the people I know on a MUD I frequent; I use full nickname replacement so no traces of the original name are left. I also tend to play-by-play hilights of the game (especially artifacts) to certain channels on that MUD, since people like to hear about the sieges and artifacts and other such interesting things. Near the beginning of the game, one of my dwarves made a pretty crappy artifact cedar scepter. It was my first artifact of this fortress, though. I went ahead and named the new legend Johan, after one of the aforementioned people.
Years, sieges, and eight artifacts came and went in that time, including an extremely simple artifact (one of my dwarves was possessed, grabbed an emerald, and locked himself in one of my shops, coming out with an emerald goblet encircled with bands of emerald) that happened to be worth 96,000 despite its simplicity, thus far my most expensive one. Anyhow, a child in my fortress was just possessed (he was already a full-fledged grower from harvesting, amusingly) and, well, I'll let the results speak for themselves:
Kizestlisid, "Zealclash," a marble amulet. This is a marble amulet. All craftsdwarfship is of the highest quality. It is decorated with turtle shell and encircled with bands of marble, cedar, dog bone and green glass. This object menaces with spikes of talc. On the item is an image of a dwarf and a cedar scepter in marble. The dwarf is raising the cedar scepter. On the item is the image of a dwarf in chrysoberyl. The dwarf is dead. On the item is an image of a dwarf in green glass. The dwarf is withering away.
Needless to say, Johan is not pleased by this prophecy. I did, however, get an extremely agile, extremely tough, legendary child stonecrafter out of the deal, though. It's also my most complicated artifact thus far, at 9 items. The previous artifact I was going to scum I gave up on quite some time ago because there's no way I could build the proper buildings and make non-green glass in time.
