I hate to do Seuss' work for him but there are some real issues with Potter sheet.

1) Chiss. While it is possible to be a Chiss it is highly unlikely, chiss reside in the unknown regions. A area of space hard to navigate and is largely unexplored. The only reason they are in The Old Republic is Vitates Sith Empire is there as that is where the Sith retreated too, which means that you'd know about them and could warn the Jedi and thus the Republic would likely try and sort out a plan of attack.

Not to mention the Chiss are only in TOR as "LolGame"

3) The Mandalorian wars are from 3964BBY to 3960BBY (Main conflict, not the Mandalorian Raids) which means... you haven't been born yet. BBY (Before the Battle of Yavin) dates go down to 0, where the first Death Star was destroyed. Then ABY starts and it goes up the way.

4) Jedi in Unknown Regions. The Jedi would encumber the same navigation problems as everyone else, most people who fled into the unknown regions were considered crazy and often left too it. Not to mention he'd encumber the minute issues of a Sith Empire

5) Barrier wouldn't be taught to an initiate, it's more of a Padwan time ability.

These are just some realllyyy big things that kinda scream out. I'll leave the rest up to Seuss, ofc I'm not GM so if Seuss says that all this is okay I'm fine with it :P
