Hey, thanks for the enthusiasm towards our games and lore! As for your future content question, the answer is yes, potentially! You might have noticed you can build your relationship with certain NPCs. Play your cards right and maybe something might bloom from that!
As for your lore question, I'm afraid I can't answer most of that just yet. I CAN say the bandits are NOT dragons though, yes.
As for the lekta auxiliary commander... you'll have to wait and see, but you're very observant to notice those things about his physicality and what he says about himself. In future updates you'll see an answer to your question though...!
Thanks again for the questions and interest!
