The Sword and Planet hero lies somewhere between the extremes of Sword and Sorcery and High Fantasy. The archetype is Edgar Rice Burroughs’ John Carter of Mars. The character of Ruenn MacLang from my Taleran books is meant to fall into this general category. Here are the characteristics of this type of hero as I see them.
1. They are bigger than life but not to the extreme of the Sword and Sorcery hero. They are fast and strong but not typically described as being as big or muscular as the Sword and Sorcery hero.
2. They also have an indomitable will to survive and can tolerate great pain and fight through serious wounds.
3. They typically do not face much sorcery. Their enemies are primarily physical enemies, although not always human.
4. They do not like violence and generally crave peace, but they are very good at violence when it is forced upon them.
5. They are much more likely than the Sword and Sorcery hero to enjoy philosophical debates and activities.
6. They are comfortable alone but are not loners. They usually make some good friends and they always have a love interest, who is usually a princess or noble of some type. They are immensely loyal to their friends and families.
7. Far from being an anti-hero, the Sword and Planet hero is always honorable and would typically be considered a gentleman.
8. The goal of the Sword and Planet hero generally lies between the extremes of Sword and Sorcery and High Fantasy. They are never out to enrich themselves, but they also are not as likely to be involved in saving the world. Instead, they must save their families, their loved ones, their home cities and home lands.
Note: In addition to John Carter of Mars, there is Dray Prescot of Kregen, a creation of Kenneth Bulmer, and such characters as Jandar of Callisto by Lin Carter and Harry Thorne of Mars by Otis Adelbert Kline.
BTW, Miladysa has a very nice review of Swords of Talera on her blog. I very much appreciate her kind words. It's always such a pleasure to know that someone enjoyed my work.
