Zohm is the energy of everything. Every object, living being, place, memory and idea is made from it.
Zohm is not distributed evenly. A common iron sword may hold little Zohm, while a blade known across kingdoms as Kingsbane may gather far more. The more people recognise its Name, repeat its story and believe in its reputation, the more Zohm it attracts.
Greater Zohm means greater power, though that power is rarely predictable. Kingsbane might reshape its own substance into something no longer made of ordinary metal. The Beneath changed in the same way. Once only a myth about an endless world below the earth, generations of stories and belief drew enough Zohm to its Name that the legend gained physical form and became a real place.
Zohm is influenced by how True Life perceives it. Skilled practitioners can channel Zohm to bend substance and twist reality. Such control is never safe: even the smallest mistake may distort the intended result, turn the power against its wielder or unleash consequences far worse than death.
During both the First Great Pulse and Second Great Pulse, Zohm increased significantly. Due to this, now even mundane things twist and change based on their Names. Even household items in private dwellings, local traditions or village tales have enough Zohm to become unpredictably powerful. This has allowed Zohm masters more power to bend substance, but the risks are even deadlier.
