My first idea is a Hero called Ser Luwin.
Ser Luwin is a well trained knight from noble family. He was born in The Citadel, but when he was only thirteen, his father sent him to Hammerhold to train with knight and warriors, hoping his son will become one of them one day. Now, Ser Luwin is a sworn and royal knight, and he serves lord of Hammerhold. In the battle, he fights with very large sword and he rides a horse.
Level 1 stats:
Health Points: 460

Abilities:
Wild gallop: His horse rushes very fast on nearby enemies, hitting them with his legs. Ser Luwin's level-ups increase duration and damage of Wild gallop
Sword strike: Ser Luwin hits nearby enemy dealing very high damage. Ser Luwin's level-ups increase damage of Sword strike.
Quotes:
"By the old goods and the new"
"I sentence you to die"
"Yiiiihay" (during Wild gallop)
"Taste my steel you scum" (during Sword strike)
There will be more ideas, probably every day. I appreciate every critic and comment.
