House Isa

House Isa is a fallen noble family of Yirsi from Anglunia. They were a small group, their founder simply known as 'Isavyr', they were born from frugal business and making connections with other prominent families through business and their arts. You see, Isavyr had been a brilliant artist, and his offspring would end up following in those steps, as would the future generations. The Isa House specialized in equisetic fabrics, dyes, paints, tapestries, and many other forms of artwork. As each Isa found their own, they dabbled their hands into other forms of creation. Despite their renowned skill, the house was quite humble, living quietly and elegantly until one fateful day.

A drug from the plant: Frostbite Thistle, or the Tilaexa'vys, made its way into the House. The drug was passed through the members of the family, and it was horribly addicting with painful side effects. As it was rare, needing specific lighting conditions and only in the deep caves of of Mirau, it was pricy and in high demand from those unfortunate enough to get hooked on it. It was that, or doing the dangerous caving yourself. So soon, their House began to crumble into nothing between the death, addiction, and losing their fortune.

Some members are still alive to this day- the few who were young enough to not be pushed into the substance, and those who survived and still experience difficulties to this day. However, even those who have managed to avoid the drug almost feel a lull to it, a call that they must resist or they'll meet the shivering fate of their ancestors.
