My recommendation would then be to try to make it historically accurate. You can check Appian in https://www.livius.org/sources/content/appian/appian-the-spanish-wars, where Viriathus' story covers from §60 to §75. I can help you with the distillation and writing of information if you need that. You could for example paraphrase Livy (who didn't write a lot about him) by stating somewhere "From shepherd to hunter, from hunter to bandit, from bandit to leader".

That sounds like an amazing idea, i don't know how many good atlas tutorials there are, but there are quite a few experienced mapmakers on the forums, I'm sure some of them can give you pointers.

This mod is good to be embed in alpha 0.29

This is the AI doing it.  I found that geometry is still very difficult, so the AI does not build anything yet.  But it will analyze current buildings and plan the fastest route to gather.

I'm working on a 3-scenario campaign with the Iberians. Little known and a story to highlight I think it could be fun and original.     The Fire of Freedom or (The Eagle's Shadow)   You play as Viriatus, a Lusitanian chief fighting against Rome.   Scenarios :   i. Unite the tribes – build your base, defend, convince villages to join   ii. Ambush a Roman supply column in the mountains   iii. Final siege – hold your fortress against Roman waves   I'm still learning the Atlas editor so if anyone has tips or knows good tutorials, I'd appreciate it.   Any feedback or suggestions!   Thanks
