You wake up one morning and find that everyone is gone. You are the last human on Earth. However you aren't alone. 1% of the worlds population is left, and are Dark Seekers (from I am Legend).
However to help you survive you have been given a special gift. You can summon anyone you know the name of (Real people only) and can picture. You can use this ability 12 times a day and each time it is used it lasts an hour. The people you summon will be friendly toward you, and help you the best they can unless you give them a reason not to, (for example if you summon Adolf Hitler, and beat him up, he isn't likely to help you next time you summon him). You may also summon actors (as long as you know their names and can picture them) as characters they have played, but they do not get any knowelge the actor themselves doesn't have. For example if you summoned Robert Downey Jr's Tony Stark, he'd have the personality of Tony Stark, but he wouldn't be able to build you Ironman armour.
How long do you survive in this new world? Is your new ability enough to keep you going?
