Hello Crispulus, welcome to the .Org and to EB .

1) EB has two EDU (export_descr_unit.txt) files: one for SP and one for custom/MP battles. These can be found in the "SP/MP game EDU" folders. The EDU in the data folder will be overwritten by these when you start the game through the trivial script.

2) If I recall correctly, the Roman triple names have been created via character traits.
