Just daydreaming about spells here: zodiac signs are practically perfect for a whole new slew of spells.
for example:
The sign for cancer summons a crab to fight for you for a limited time.
Aquarius could be a water blast spell (possibly short range but area damage?)
and the list goes on…
I the idea. There is a lot of potential for various spells. Not only can you add the zodiac but the elements for each zodiac sign. Fire, water, air, earth. Then there is Qualities to each sign Cardinal, Mutable, Fix. Maybe, a way to add that by introducing diplomacy in the game. Especially if faction is added. All future ideas, I like the concept.
so we still have the rest of the futhark alphabet left and there upgrading the pet system soon so thay may one day add other animals as pets or a combat system for the pets.
