To start, there are seven different factions in the game, each representing a different concept:
- Solis (Orange), representing gluttony. Solis allows you to force the opponent to consume their own resources or consume your own for a burst of power.
- Luna (Yellow), representing greed. Luna is focused on gaining resources, primarily through card draw.
- Ignus (Red), representing wrath. Ignus is focused around combat strength and eliminating opposing servants.
- Aqua (Blue), representing envy. Aqua revolves around strategy and control.
- Silva (Green), representing sloth. Silva focuses on slowing down the game and playing strong creatures to overpower the opponent.
- Aes (Pink), representing lust. Aes allows you to take control of enemy servants and switch their positions.
- Terra (Purple), representing pride. Tera cards are physically weaker and often take unique routes to battling the enemy rather than fighting them head-on.
The Caster Chronicles is a very different game then Force of Will. Although it still involves playing creatures (called Servants) and spells (Conjures) by using mana (which is referred to as Aether in this game), the core gameplay mechanics are very different. Your Aether is generated by cards known as Casters (equivalent to magic stones or lands). Following the trend of Magic: The Gathering these are shuffled into your 50 card deck and must be drawn and played from your hand. Also like Magic, they can only be placed once per turn. This is where the similarities between Magic and Caster Chronicles end as you are able to play cards from your hand facedown to produce colorless Aether should you not draw enough casters.
