all the normie stuff. and i want the model to be created with ai and used over multiple outputs.
You can make a LoRA and use it as many times as you want,
even for photorealistic characters. Drachenlord and Lightbringer should be entirely doable.
Making image gens that are consistent in their look and style isn't that difficult nowadays, attempts were made to streamline the process and I found some good guides online. If you'd like to make models (LoRAs?) of Drachenlord and Lightbringer, this could be done in two ways - training your own LoRAs or making prompts that roughly resemble them and reusing those instead.
For local training
this guide covers a lot of information, starting from making a dataset (in your case it'd be finding 20+ images of Drachenlord online and cropping them to the right resolution), how to curate it (telling a tool to do it for you) and then training it all locally (NAI 1.5, PDXL or Illustrious, software is linked w/ presets, zero thinking required). If you don't have a computer for it then you can give any of the online services a try, though be wary they'll most likely hold your credit card info hostage and change up the payment plan without you noticing.
Civitai will charge you a bare minimum of $5 for their service (500 Buzz to generate an image then a varying price for on-site generation), but it seems to be the safest choice.
As for a choice of checkpoints, depending on your preferred style you could either do realistic gens on
Flux,
Stable Diffusion, Pony (not recommended) or a cartoony/weeb style in
Illustrious. Flux is the safest choice if you want real people to do things together on one image. Natural language works best with Flux and Stable Diffusion, you can spell out what you want and it'll roughly understand it, while Illustrious was trained on an anime porn website and works best
with Danbooru tags.
I think that covers everything I know. If you want to have an easiest time, then just pay Civitai and use Flux.
