Epic War Age (EWA) - Adapted Mod Collection

How is that possible?

Ideally, it's not possible without expanding the arrays with IDs. To fully add a faction, you need to add IDs for cities, buildings, hero types, units (as in .ncf files), and it would also be good to add ability IDs for creatures, at least to create copies of old ones with new stats. IDs for skills and abilities would also be useful, even if only to create racial skills for new cities using scripts. I'm not sure if they're needed, but most likely they are: IDs for adding defense areas for new cities, dwellings, maps of the Tears of Ash, city specializations, maybe I missed something else. But for this, it is necessary to disassemble and edit the .exe file, since no one has released the source code, and it's all quite complex. But if there are skilled people, I'm all for this development path for the mod.
