The Fae are inherently tied to the seasons, the cycles of change that flow through the world a part of their blood and bone. Soon after the Godswar, some clever Fae — their exact nation of origin lost to history, though many scholars still debate it — came up with a means of harnessing those cycles in ritual and spell, invoking the Seasons themselves to power their magic. Over time they taught these secrets to others, including non-Fae, and in modern times mages who seek a connection to the cycles of nature often choose to pursue the path of the Invoker.
Invokers fashion objects with links to each of the four seasons, using them to call upon the powers of Spring, Summer, Autumn, or Winter. These talismans are arranged in a circle during a ritual invocation, called upon in a pattern to build up to the intended effect of the ritual. Spellcasters wear their talismans on their person, channeling energies from them and into their spells during battle by invoking the name of the season and the aspects of it that they require.
The preparation and consumption of drinks with seasonally-relevant ingredients is often a part of longer rituals, though each school of Invokers has their own preferred recipes for a given season. Rivermark sorcerers greatly prefer spices and wine in their ritual libations, Faen’miir invokers almost exclusively drink straight herbal tea, Sunderwyl invokers have a tendency to experiment with odd ingredients in their brews, and Dalean invokers enjoy fruit juices and beer as their ritual drinks.
If you wish to play a seasonal invoker, buy or construct talismans to use for each of the four seasons. These can be items that you wear, or ones that are placed in a ritual circle, depending on what uses you’re planning for them.
