Spiral HQ/ Elite Spiral HQ/ Sports Stadium/IndoorSports/ Skill System for Knights - Part of the suggestion for a Spiral City

Please place comments at this thread
NB: This is a suggestion part of the link above
Spiral HQ/ Elite Spiral HQ
The Spiral HQ is what I think the mission entrance (possibly) should go.
The Elite Spiral HQ is part of The Spiral HQ - just that the entrance is hidden in The Spiral HQ, only accessible by Vanguards.
Spots Stadium and Indoor Sports
The Sports Stadium basically hosts different sports related to the season we are in.
The sports are:
Football SPD +2 (Spring)
Cricket ACC +2 (Summer)
Ice Hockey STR +2 (Autumn)
Snowball Fight STM +2 (Winter)
IndoorSports hosts all the sports whatever the season (since it is indoor). Here are the sports:
Sprinting SPD +2
Long distance running STM +2
Bowling STR +2
Shooting ACC +2
The abbreviations after the sports are what type of skill of your knight it increases.
Here are the skills:
Speed
Accuracy
Strength
Stamina
Also, you get points for your natural defence for each sport you play (at random).
Natural Defences:
Normal
Piercing
Shadow
Elemental
You get points for these from playing sports games (random type and random amount).
I love this idea for the "Spiral Empire" thing you made! I so envy you for making a bunch of wonderful ideas!
