1) Commander

2) A bug, if he's really dead. If he just e.g. "Vanished between space and time" or something, and later reappeared somewhere (probably insane), he'd still be alive even though you might've thought that he is dead already.

3) Known bug. Alt-Enter twice works as a workaround IIRC. Myself, I play Dom3 in windowed mode, but maximized.

4) With a Marignon/Pythium national spell Heavenly Choir. The manual lists the spell as giving other commanders as well, but currently the other angels appear as units instead.

5) High Seraph of Caelum is better than a Seraph of Caelum. The six-winged, angelic being that is also named Seraph is more powerful than most mortals, immortals, humanoids, monsters or summoned creatures. Seraphs of Caelum (latin for "sky") were named Seraphs long before Seraph as a six-winged angel existed in Dominions, but the root of the name is probably in the angelic being who commands great magical powers.
