Players will often ask around in towns and villages trying to find out useful information. This lists 100 different rumours for them to hear.

The rumours may or may not be true, at the GM's decision. They can simply be used as background flavour to make a setting seem more alive, to hide important information amongst the dross or perhaps as adventure hooks themselves, if they are fleshed out.
