Oh. For me, I am rather liberal with pleasantries. They are just words, after all. One can give me a request like 'fuk u giv me ahheal' for all I care.
However, I'm not sparing towards proper naming.
Say 'niff' and I will simply assume you want Niflheim City. And it is a pity most that come by me give it that name. The last time I saw someone that gave a close enough word to it(Hvergelmir's Fountain(Trunk of Yggdrassil), or even Skellington if you wanna) was 'ygg'. Simple, short, and it was about 6-8 months ago.
