If every Paladin has a deity, do Oathbreakers have a deity, or they leave the faith behind along with the oath?
And if they leave the faith behind, where does their power come from? Shouldn't evil gods impose tenets among their paladins too?
It seems to me that concept of oathbreaker is about letting go everything, and you still get powers.
As for Paladin and Gods, i think in the final release you will pick a deity just like with cleric.
Oathbreaker is a Paladin who was corrupted away from his/her ideals either by an "evil" power and/or personal ambitions. They don't have Oaths, but what made them fall is usually what "binds them" and dark powers will gladly act as intermediary even if they aren't actively worshipped, they love to corrupt mortals. But Larian, since they removed alignments, presented Oathbreaker as a neutral choice, but one look at their abilities and they are clearly supposed to be evil:
- aura of hate buff undead and fiends
- the capstone ability is called "Dread Lord"
In the Forgotten Realms, the greater powers (gods, devils, demons) often mettles with mortals affairs even if they don't show themselves or communicate directly. Having followers or pipping the dices to manipulate mortals is a thing. And they can interact directly too, even if you don't actively worship them. In the early access, you can get Lolth to remind you to not impersonate her for example.
Evil gods can have paladins with oaths, these are not Oathbreakers. The Oath of Conquest is tailor made for evil gods, especially lawful evil ones. Vengeance work, if you use the point of view of the god/player instead of the alignment system to apply "justice".
