Harmony - Troop Symmetry

P.S. Destruction magic = Chaos magic; primordial magic = summoning magic. P.P.S. I also considered this option: since the Inferno guild in any case duplicates some other guild, we can give them something else – for example, give them not darkness + chaos, but chaos + summoning – this would reflect their inclination towards primordial magic (according to the lore, primordial magic is closest to them, followed by fire magic and then darkness magic). Also, this way we would equalize the number of guilds with light magic and with darkness magic (3 against 3), but the thing is that demons without darkness magic seem strange to me, and it is also canonical, so for now I will leave them with chaos + darkness.
