So you like, fall into a wormhole that takes you to a random time with random powers. Just go do this stuff:
Roll a number between -5000 and 2020, what number you get is the year you end up in (the negatives are the BCE years)
Now use the Random Page thing to get as many random powers as you want(but you have to keep all the powers you roll, even if they are actually more of an impediment that a power)
You don't have to keep any OP powers you get if you don't want them
