YAGS Fantasy

YAGS Fantasy covers generic swords and sorcery settings, as inspired by various flavours of Dungeons & Dragons and its various spin offs. Magic is common and flashy, monsters are large and lurk in dungeons and wilderness regions.


Magic in YAGS Fantasy is split across seven mysteries which cover the various elements as well as concepts related to them (so Fire also covers movement and speed, as well as heat and flame).


Sorcery is natural magic, that does not require academic study. It is the magic used by magical creatures such as dragons and Fey, and also the magic of humanoid shamans and village wise women.


Wizardry is academic magic, taught in schools and written down in books. It is harder to learn than sorcery, but capable of more flexible and complex effects. Learning wizardry makes sorcery harder to use, since it forces the casters mind into a more formal and restricted way of understanding the mysteries.

It is more likely to require props, words and gestures than sorcery does.


Humans, Elves, Dwarves, Gnomes and Halflings are common in YAGS Fantasy, as are other intelligent races such as Orcs, Catfolk and various crossbreeds.
