DD: Then?
DD: It wouldn't be "then".
DD: It technically should be "before".
DD: Since the thing you would be doing, in the future on your perspective, would be before when you had time traveled.
DD: I know, time grammar isn't your biggest concern, but it should be.
DD: I don't know what the lordling prototyped, but that must be what is causing you time traveling.
DD: And in order to have the ability to time travel, you need to time travel and force yourself to time travel.
DD: It all makes sense.
DD: So, before you time travel, before you decide abruptly to obtrusify the timeline, you should destroy the Tower of the Lordling.
DD: Even though he isn't in it, there's a different purpose for that, something much more, enigmatic.
