What happened? How did he manage to get himself killed?
Also, how did he manage to find someone to bring him back to life...?
Yep. 'Grüße' means 'Greetings', and 'Tach' is 'Day', as in the shortened version of 'good day'. Most folks in there are German, but at least there are a few people who speak a reasonable degree of English.
And remember: To switch between languages (common language and dwarf language, since we're dwarves), use the "!l [language]" command. So, to switch from common to dwarf, use "!l dwarf" (no quotation marks, of course.
Make sure you're doing this in regular speech mode, and that you're not shouting or whispering. Otherwise, it will ignore the script command and just shout/whisper out "!l dwarf". I did that recently, shouting out in a strange tongue across half the city. And then I couldn't spell properly for several minutes after that.
By the way, if you find that trader with the cow again, Merigon-something? Don't trust him. The man's a bloody thief, and will always try to make an unfair deal in his favor. Of course, that is how a merchant is supposed to act, but just be careful you don't undervalue your goods, like I did. He tried to sell someone 60 onions for 170 coppers, which is most certainly not a fair price.
