M2-player

I was playing this game and I noticed that there are names natively using in middle or/and east Europe e.g. Ludmila (Ľudmila), Marek, Katarina (Katar?na), Vaclav (V?clav),... I'm from Slovakia and this are Slovak (or maybe Czech) names. Obsidian is American developer. How did you came to this names and why did you used them? It's nothing personal. I'm just curious
