The Way of the Druid
Making their homes within the Deep Forest of Britannia's northwest, the mystic druids call the town of Yew their own. They can frequently be found in deep meditation amongst their sacred oak groves, which they defend fiercely from all who would harm the forest they protect. Deep within these woods, they further themselves in the virtue of Justice, and are frequently involved in the affairs of the High Court. The druids' knowledge of natural lore is without peer, and their understanding of medicinal herbs and the habits of Britannia's wildlife makes them a boon companion. This, along with their powerful mystic arts and knowledge of the arcane, makes them a valuable asset in any adventure.
The druids fight with an assortment of weapons, although they often prefer to wield different types of bows, carved from the trees they carefully nurture. In close combat, many prefer a stout oak staff or heavy mace. The druids tend to shun works of metal, preferring well crafted leather armour, for they believe in retaining a close communication with nature; although, some have been willing to put aside their convictions to further a greater cause.
In Ultima 2 in the town of Baradin. The druid in a grove of trees shouts, "Anol Nathrac Uth Des Bessod Dien Doch Dientes!" This is a reference to the charm of making from the great movie Excalibur (Morgana recites this in the movie). Translates to "Breath of serpent, spell of death and life, your song of making."
If you take this further and look at Jones Celtic Encylopedia - In irish it is spelled, "Anal nathrach, orth' bhais's bethad, do che'l de'nmha" or "Anáil nathrach orth bhais betha, do cheol déanta". Translates to "Serpent's breath, charm of death and life, thy omen of making."
The Druids are fierce fighters, especially when defending their beloved groves. They hold all trees to be sacred and their town of Yew lies deep in the woods. Druids are also impressive practitioners of the mystic arts and their knowledge of herbs is without peer. They may fight with different types of bows, although their preferred weapon is the mace. The Druidic philosophy forbids the wearing of metal of any kind, so Leather is their armor of choice. The Druid's knowledge of the ways of the woodlands make them invaluable as fellow travelers.from The History of Britannia (Ultima IV)
We are now seeking a contingent of druids to join us in the Abyss. We hope they might be able to use their mystic abilities to persuade a sacred grove to take root in our chasm. Many druids are skilled with bow or mace, and so would be doubly useful. Druids generally shun the wearing of metal armor. Here this is good, for in the Abyss sound carries easily, and metal armor is noisy.from Memoirs of Sir Cabirus (Ultima Underworld)
Because of their devotion to and understanding of nature, druids are a much-needed profession after Britannia's time of environmental devastation. Most druids do not go heavily armored, and rely instead on their mastery of spell-casting and woodcraft to evade combat, or utilize their surroundings to their own tactical advantage.from A Safe Passage Through Britannia (Ultima Underworld II)
