Fire!

Valery looked at the city of Greenwood, she looked at it carefully and with nostalgia. She has come here more than once, as have Katerin and Maria; they have all come here more than once and have also visited each other's territory. 

They have played in the arboels and know the ancient cities and visited when the cities were opened on the surface. 

The first time they visited each other's cities, they were just building the walls, a few houses and the trading area. 

Now it was totally different from when Valery and Katerin came for the first time, the walls were already finished, now too and there were many more houses finished to build but there were still houses under construction, the commercial area was almost complete. The roads are under construction, but they are nowhere near finished.
