—Alder talking about the Dawn Brigade with Jarod
Alder was General Jarod's main subordinate in the Begnion Occupational Army. In several instances, he appears talking to Jarod before and after battles. He has high reverence towards Jarod, as shown in his death; killed by the Black Knight while defending Jarod, sacrificing himself by leaping in front of the blow.
- Judging from his illustrated and map appearance, he is likely some type of tier 1 armored knight, but it is not revealed to the player what type he is, as he is never seen holding a weapon on any of his map appearances. However, by exploring the internal data from Alder's map appearances, it can be seen that he has the data of an Armor Sword.
- Alder is the only antagonist in Fire Emblem: Radiant Dawn that you never fight in battle, because he is killed by the Black Knight before you could fight him.
