One common theme is probably heroism. Given the 'War' aspect, the characters, including Uriel, might be depicted as heroic figures facing great challenges. For example, they could be saving a world or a group of people from destruction.
The exploration of power and morality is often seen. In a war - torn setting, decisions about using power and what is morally right or wrong become crucial. Uriel might struggle with these concepts, and fanfiction writers could delve into how he makes these difficult choices, whether it's about using his own powers for good or not succumbing to the dark side when faced with tough situations.
One possible fanfiction could be about War and Uriel teaming up to face a new, unknown threat in the Darksiders universe. Maybe a powerful demon that has emerged from a previously sealed realm, and they have to combine their unique abilities to defeat it.
One possible scenario in such a fanfiction could be that War and Uriel start off as reluctant allies. War, being the Horseman, is initially focused on his own mission. But as they face various challenges together, they begin to notice the strength and determination in each other. Uriel is impressed by War's unwavering resolve, and War starts to see Uriel's more compassionate side beneath her tough exterior. Their relationship could develop gradually, with small moments of shared understanding and mutual respect, eventually leading to a deep romantic connection.

Perhaps there is a dark force corrupting the angels, and Uriel is suspected of being influenced. War is sent to investigate. As he gets closer to Uriel, he realizes she is innocent but they must work together to find the true source of the corruption and stop it before it spreads throughout the entire angelic realm. This would involve a lot of action and tense moments as they fight against both the corrupted angels and the real threat behind it.
In a War and Uriel romance fanfiction, the element of forbidden love could be significant. Their different allegiances, War being part of the apocalyptic forces and Uriel an angel, make their relationship something that would be frowned upon by many in their respective worlds. This can lead to secrecy and the added excitement of being discovered. Their shared experiences in battles and facing common enemies is also crucial. These shared moments of danger and survival can strengthen their bond, as they rely on each other's skills and abilities. And finally, the exploration of their individual backstories, how they became who they are, can give depth to their relationship as they understand each other better through these revelations.

One common theme is the re - evaluation of historical events. Writers often use the perspective of a historian to look at battles or wars in a new light. Another theme is the exploration of the human side of war. Historians in these fictions might focus on the experiences, emotions, and motives of soldiers and civilians. Also, the search for truth in history is a big theme. The fictional historians are often on a quest to uncover hidden or misrepresented facts about a war.
Power is a common theme. The bringer of war is often associated with great power, and fanfictions might explore how that power is used, abused, or controlled.
