Since he met  Willan, Cadeyrn has embraced the nomad life of an adventurer. It meant for him, even if he's not a warrior, to have comfortable and practical clothes, not too hot, nor too light. As he's not used to armor or melee combat, Cadeyrn rely on his moblity and Willan martial prowess, hence his light outfit.

Much to WIllan dismay, could he not pass on some classy but onerous garment, as he don't like to be dressed like a lowlife especially in town. After all, he can write and read, he's well educated : even if his life was hard and did he fall once in disgrace, he kept his pride in his scholar talents. And his magic, but shhhhhh... It's a secret !

But even without weapon, Cadeyrn is not dead weight for his comrade Willan. Helping people and living on these actions, the liger's general knowledge and eldritch affinity are precious skills and tools for their team as their environment and missions varies much, according to the needs of those willing to pay them.

In his satchel, can he find many pockets holding a small knife, a fire lighter (steel and flintstone with a tinder), some medicinal and culinary dried herbs, many seeds from different species and finally some scrolls or a diary with calligraphy tools. For heavier or larger stuff does he rely a knapsack for bigger travels.

Again, I must thank  Quirachen for her talent ! Go check her art !
