Here are some Heroes I use for the Fantasysaga Maps. In the Wiz-Folder are three Wizard-Portraits. One of them is also in the Hero-Folder, but the picture was a huge one -> PERFECT for a wizard!
Copy the Thomas-File in your User-Folder and you can select in the Editor->Heroes->Files (Icon on the left there) this File. Here are all Heroes ready for your map. The Hero-Storys are in German (Sorry), but you can write a new one of course!
