In return for his help protecting them they handle the boring politics and hang out with him in there spare time. Besides he doesn’t want much other than for them to be able to eventually protect their country without him

im also wondering why luna and celestia haven’t asked the million bit question of nemo yet…there both seemingly born protectors and love to give of themselves for others and are already well versed in being ageless or near ageless and heck hes made them part gaurdian already soooo…why havnt they asked if they can make it a full time thing, especialy now with twilight and company geting the ball rolling on prety much replacing them as equestria’s full time protectors at this point in history…hes helped them so very very much over the years…youd think theyed wana return the favor.

@Prysmfox  
Well Nemo isn’t like those guardians. He remembers everything

im quite fond of this comic so far, it is a silly and interesting twist on things
 
but arn’t gaurdians supposed to loose there memory every time they shift worlds…[see the game ‘arx fatalis’ if you dont get it i think the gaurdians in ultima worked the same way)
