Gnomish shortcut chains

As rumour has it, the gnomes have been using shortcuts to get around Runescape. Most of the time it's a squeeze for us big humans to use the gnomish shortcuts but with a bit of exercise they will save us some time too. The stepping stones in some rivers clearly cannot be shortcuts used by gnomes. We have problems sometimes to make the jump from one stone to the other, let alone gnomes with their short legs :-) Also the spikey chains that can be found in the castle north of Canafis are not likely gnomish in origin. Their links are quite big and can cut open your hands badly even when wearing gloves. A gnome would loose a complete hand if she was not very careful with these, maybe a reason why I have yet to spot a gnome running around in that castle?
