RTF is a global modification that replaces all towns in the game.

Perhaps Simagl, the green bird with nature magic, would be a better choice? As for abilities, "Entangling Roots" or "Hive Summon" (not to be confused with the Swarm) could work.

I agree. It would require less thinking about the design :)

No, I don't think a light green color suits them.

Something like this? I think they should be adorned with herbs, and then we can add effects.
