Well, everyone who comes here has to adapt their character to the timeline. Keeping Mak's birthdate the same and having him sleep for seven hundred years is a perfectly valid way to do it - but he wouldn't know anybody and nobody would know about him. On the other hand, if he was born, say, 635 ABY, he could have been imprisoned in cryosleep for only a handful of years and would still have his relationships, positive and negative, intact.
