Twisted Branch Apothecary

"The plants of Rûl contain many strange and wondrous powers, waiting to be discovered through the hermetic magics of Alchemy,. The eldest leaders of Witchcraft and the hightest ranking alchemists of Lij remember the rare components and detailed preparations needed but only a few of most powerful potions. The rest remain lost in great volumeds of formulas written in the time of the witch King, now buried in decaying libraries. One Clockwork alchemist is driven to devise the formula that can cure their terrible condition and restore their soul to a human body of flesh and blood. And Gauge will find a cure no matter the cost."
