"Two Seasons: Winter - Spring 2017-18". Online games.

Managed to gather a lot of Nagas, so even without Mermaids, by the middle of the second week, I had almost 40K and resources comparable to those needed for Archmages and Grand Mages. I took the purple castle, and not far from there, I found a teleport to the green castle, where I defeated Sanya thanks to scouting near Tazara. Thanks for the game!
