Prince Lucas: a summoner fanfic

What if King Harold had a child, Prince Lucas? His wife dies in labour, and he himself is killed later in the year fighting on the orc front. This is a huge blow for Hominum, as two of the most well loved monarchs are killed.

16 years later
Prince Lucas was raised by old king Alfric. A very strong summoner, by the age of eleven he had a summoning level of 14, the strongest ever for that age in Hominum history. Though brought up to hate the dwarves and elves, he did not. At 16 his summoning level was up to 34, and increasing as he improved with his demons. But what happens when he has to go to Vocans academy?

I know that in battlemage King Alfric died, but in this King Harold did instead.
