They could have sent word via Groffel. For having tiny legs they manage to get a message through quickly
I find this whole Groffel thing completely unrealistic... I doubt that someone who was just killed could write a whole letter, attach it to a groffel, send it through the Death Realm to the living realm, right to his/her/kras guild mate, and said guild mate will gather up the whole friggen guild just to attack one person, and suddenly they all appear before the killer within 30 seconds after the murder... Ridiculous.
Even if someone was robbed, it's not like they're going to recognize the thief (most people like to hide their identity when doing things they shouldn't be doing). And I really doubt you can write a letter and send a groffel
while you're being robbed.
GMs should be able to punish for behavior like that. It's dumb. Imagine if it were real life. It would be dumb if you were attacked in a dark, secluded alley, and suddenly the whole police force, and the army, and your family, and your relatives, and all your friends, and Chuck Norris (of course he could do this alone), and Jackie Chan, and Buddha, and kungfu!Jesus, and angry!Ghandi, and Pikachu, and Bigfoot, and Chupacabra, and Mario and Luigi, and Link and that dumb fairy, and Gandalf, and Indiana Jones, and Master Chief all came to save your insignificant, pathetic little arse. That's how ridiculous it is.
It should be obvious now that I hate people who do stuff like that.
