So, I am building a small army using Urban mammoth, Warmachine and GW pieces to use as enemies for My Sons of Horus to fight.
I am considering using the Eldar codex as rules for them, I was wondering what others have done for their own projects.
Im also in a pickle as what to call the system and army , but I assume since not every battle and Crusade was recorded we have some room to flex out own mythology making for Non Imperial and xenos armies...
