[DGD] time travel

[Dread Quixadhal]

There's also the question of abuse of the system, if it's anything
other than a heroic undertaking to accomplish time travel. :)

Sure, going back in time to change history, so that your party slays a
dragon before it burns down a city, and then returning to find that
the city in question became an iron-fisted regime that enslaved all
the neighboring communities, and that nobody has ever even heard of a
dragon... that could be fun!

However, if I know players, what they'd end up using it for is
collecting 1000 steel swords, selling 10 at 10 gold each, then when
the price drops to 5g due to oversupply, travelling a few hours back
in time to sell another 10, and repeat until they're out.
