Here is a summary of my thoughts on House Diedne (if one of my player from the "Alliance de la Vouivre" read this, please stop here) :
Base Hypothesis :
- Diedne are from a druidic legacy (that is pretty much everything we know about their house)
- they were strong in Britany ?, and surely mostly concentrated in the following tribunals : Loch Leagan, Stonehenge, Hibernia and Normandy
- according to the major virtue named after them, they were strong in "Spontaneous magic"
I am no specialist in celt and gaul history but here is what I understood from reading different books, and made some decisions for the Diedne :
Diednes are the heirs of the priests of celtic culture. Because celtic people were integrated by the romans from 50BC to 400AD, and then they were persecuted by the christians, their followers dwindled from -50BC (vicotory of Cesar on the Gauls and then the Bretons) to 767 AD (foundation of the OOH)
I suppose that because they used mostly oral transmission of their knowledge, the ogham only appearing in the III° century, they lose much during these 8 centuries.
Before 767 I picture them to be a scattered and dwindling tradition, living like hermits in the deep forests and mountains of the gaelic lands. Once Diedne sweared the oath of Hermes, they grew rapidly in numbers and in power, still staying isolated from the mundanes and the Dominion. I figure that they would try to recover their lost legacy from the ancient celts, looking for ancients places of power, lost rites to please the gods of their ancesters, lost artifacts...
There were dozens, if not hundreds of celtic gods. Some even think that the gaul god "Teutates" (god of the tribe) was a local god specific for each location, each tribe. Also, I think that because of their pagan legacy, Diednes should be more like pagan priests than scholars.
After initiation (the 15 or more years of apprentiship) the young Diedne Magi has to choose a "path", meaning that he has to become the priest of one of the celtic gods.
From what I read in Realm of Power : Magic and Faerie, gods are sometimes magical creatures, but more often faerie entities. It would be logical that celtic gods be faerie powers because their craving for sacrifices and worship. My decision was to make some of their gods, faerie, and some other more ancient and powerful, magic powers. This was to not overlap too much with House Merinita.
House Diedne is looking for the roots of her legacy : the very foundation of their beliefs. For them, faerie and magic powers are the same, some are related (parent to children or husband to wife relation) and other are not. In the end, their purpose is to create and strengthen the bond between their magi and these ancient gods. Thus, after choosing a god from the core belief of the celtic panthon, a Diedne Magi can create a personnal bond with a lesser "god".
Celtic main Pantheon :
(here is my main trouble : to find clear attributes for each of the main gods, that can be used in game for magic focus or potent magic)
- Lug : light, summer, polytechnician?
- Dagda/Sucellos : (scholar?), fertility, forest, agriculture
- Morrigan : war, death
- Cernunnos : spirits, necromancy, renewal, horned animals
- Belenos : healing, sun(light), beauty
This first initiation grants a major potent magic with one of the god attribute.
Celtic lesser gods
(some examples from the Tuatha Dé Danann):
* Boann
* Banba
* Brigid
* Creidhne
* Danu
* Dian Cecht
* Donn
* Ériu
* Étaín
* Fódla
* Macha
* Nechtan
* Aes Sídhe
* Bean Sídhe
The Diedne magi has to find and bind the lesser god much as in the theurgic spirit familiar would do (the mechanism and calculations are the same)
History of House Diedne
52 BC : Julius Caesar victory over the Gauls. The Roman empire, encouraged by the roman cults (cult of Mercury..) begin to integrate the celtic religion into their own (lug is associated with mercury, Belenos with Appolo...) Most Druids flee to Hibernia and Great britain.
-50BC to 767AD : weakening of the celtic religion from the roman empire and after 300AD, also from the christian religion
There may be some rare text about the celtic rites and mythology in roman or greek
IV° century gham alphabet
V° century : conversion of Hibernia with the arrival of St Patrick
The last druids are like some hedge magic tradition : isolated, weak in numbers, opposed by the Church.
767 AD Diedne take the Oath of Hermes with the other founders
807 Tytalus disappear, some say that he tried to free the magic pagan gods emprisonned by the faeric pagan gods during the titanomachy and gigantomachy
851 : Tribunal of Britany : the Primus Diedne, Obregon decide and announce that the Hibernian Diedne will respect the Oath of Hermes but will do so from their Covenants and not interact anymore with the other mage from the Order (especially in Hibernia)
961 Corruption of House Tytalus
961> : Primus Diedne Ailean insult Primus Tremere Cercistum in public
House Tremere declare war on House Diedne with accusation of diabolism and human sacrifice
House flambeau join House Tremere in the war
1000? The Order renounce House Diedne
I like the idea of sacrifice exposed here (sacrifice humans of animals to gain some vis to power rituals or enchantments). I'll think about integrating it into my work.
I would be glad to discuss any point I exposed here, as I am not entirely happy with some points (like the main gods attributes)
