Creating Mawdrey
You can purchase only dragons reach part 2 as far as I know and you do not have to play any other episodes.

I can confirm, on my second account I only bought Dragons Reach part 2 and created Mawdrey.
I suspect it depends on how old your account is as accoutns that werent around/active during season 2’s release may need to purchase the complete season 2 pack where as active acounts during season 2 can still buy chapters for 200 gems each.
Anyway, the complete season pack price depends on how many episodes you already unlocked I think.
