Brimstone

A folio of the realm
Brimstone

This is the rock that burns or, more to the point in Sorcery, explodes. A virtually limitless source of power dwells within it's etheric composition.

Originally appeared in Ultima VIII: Pagan as a Sourcery reagent, it was to have been used in Ultima Online as a reagent for the (originally canceled) Necromancy system.

Additional Details

Brimstone is related to the common Magery reagent Sulfurous Ash, but is the pure unburnt form of sufur.

This reagent currently has no use in Ultima Online.

Lore

From Ultima lore:

<div style="padding-left: 3em;padding-right: 3em;">

This is the rock that burns or, more to the point in Sorcery, explodes. A virtually limitless source of power dwells within its etheric composition.

- The Chronicle of Pagan (Ultima VIII)

Brimstone is a volatile substance, and confers this to Sorcerous enchantment in the form of raw power. Be careful in your use of this reagent. Never use more Brimstone than your spell calls for.

- Vardion (Ultima VIII)
