Why does Astrologian have a Sword Sheath?

Could someone explain why Astrologian has a giant sword sheath on his side?

Ooooh I see the cards on it now... but the cards unfortunately don't disappear from it when you pull your globe out and the cards are floating around it.

idk aesthetics I guess, but it is just a cardholder that looks pretty nice on the hip

I'm more concerned with the stupid distance from your back the star globe sits when sheathed.

Holy hell that's distracting.

Okay.. but why is it never used when i choose a card? Or is that something that happens later?
