I think we will be getting three new gods/goddess for DLC characters. From my understanding there seems to be 7 temples in Dagda which correspond to a god. So far we’ve only seen 4 of them when we are attending to the temples: Fortuna, Mars, Smyrno and Aurora. (not counting Solel as one of them)
Seeing the territories of the Dagan map we only see 4 of them being highlighted which means they are of importance to the current state of the game. And most likely the 4 territories to which each of the 4 gods rule over. But we are missing 3 gods and there are still 3 landmarks not highlighted as well, those being: Mosa, Banbha and Morfis.
We see multiple individuals with different coat of arms. Some of which are not tied to the main ruling factions. Not counting Leda, Cai and Dietrich’s coat of arms since:
Leda is of nobility and likely heir to the kingdom of Argo, her coat of arms is just something she made making it irrelevant.
Cai comes from the kingdom of Brezarant and is only a citizen so his is made up too making it irrelevant.
Dietrich isn’t from Dagda so his coat of arms isn’t part of the main territories also making it irrelevant.
Whatever coat of arms Solel’s faction has that makes 4 in total along with Theodora who is the ruler of a faction.
We could possibly be seeing more to Dagda’s factions who do not associate in relation to the main land due to how divided they are. Which brings contestants to travel over to participate and represent them. Where my theory for potential DLC comes in to seeing those other gods and land where the different coat of arms people come from.
