Since Theodore has the Saturn Robe, I've been thinking of various scenarios that would be good for a time loop that also involve space travel and/or magic.
So far I thought of a few basic ones:
Simon and Lana are both in peril and Theodore must save them both. Originally Theodore doesn't believe he can do it, with the danger so imminent, he believes he will only have time to save one of them, but eventually he finds a way to save both of them. (Exactly how hasn't been worked out yet)
One of Teneber's three generals (haven't figured out which one, probably Shadestar) is after one of the Hearts of Aurora, and the only way to catch up to them is time travel. Both Theodore and the general can reset the loops, however neither of them knows when the other will do so.
A once in a millennium celestial alignment event is occurring, and Theodore always misses it by mere minutes. If someone is at a certain place on a certain planet during the event, they will receive some sort of celestial blessing. Theodore wants the blessing not for himself (since he already has time travel) but for his brother.
