The World of Deep Puddles is fun I promise! It's a tad complicated at points but nothing too messy.
Effectively it started as a far future Warrior Cats concept. About 40-50 years later new ranks are added due to drastic shifts in cultural and spiritual beliefs. Riverclan began to fear the moon since it controls tides leading to the rank of Moonchaser. Shadowclan applies similar logic to the sun giving birth to Sunchasers. Windclan has leaned into religion so hard that they now look to the stars constantly for any hint of guidance, those that read them are fittingly called Star Readers. Finally to cap it off Thunderclan has taken up dyes and other crafts creating the Crafter rank.
