Figured I'd put a vowel in front and one at the end and try to guess the consonant. That led to SH-OB.
But it had to be 6 letters, not 5. So I needed an "S-C/H/L/T" to start, so just left the H in there. SH--OB.
Started with A. SHA-OB. Shalob sounded ridiculous, so I stared with an L in the middle. And apparently, that was close enough.
The odds of arriving at that must be a gajillion-to-one. I'm still shaking my head at this.
Somehow I decided it might be a good idea to end in lob, being organic and all. Felt silly but had no other ideas, atleast I didnt try blob,..(and cab and hub seem not so likely even for fantasy words) Also felt like there might be a joke about size, so did smallob, then realized it was still to many letters and tried smalob. From that I unaware casually tried shelob (I guess following s-consonant-vowel) And was shocked it was right!!
If I copy the german city clue to google, even google throws out München as answer.... but not accepted. Typical quizmaster.
