As I know, to add new NPC or object to the world, you should add it to .lrentdat archive. But how can I do that? Is it possible to do this using modkit or g3dit_1.7? Could someone provide steps how to add new NPN template to the Gothic World?

With G3dit you can simply clone already existing NPCs (attachment). If you need more specific information, you can ask any time.

Could someone provide steps how to add new NPN template to the Gothic World?

Why do you need a new template?
(Creating a template is not required to build new NPCs.)
