He trained the prince/princess in how to use the sword.

He toughened their spirits so they could stand against the enemy horde.

He was a true hero, worthy to train another.

Helping them in their revolution to overthrow their brother.

He helped with every step of their coup,

He knew how to make allies and other strategies no one else knew.

He stood by Albion's new ruler when their brother was defeated,

He put the crown on their head and gave them the throne to be seated.

He even stood against the darkness as long as he could,

But he eventually gave in, like many knew he would.

A man with a soul, not indominatable but strong.

Who is this friendly hero who' sword is long?
