I use to play this games for couple of days... I'm now at castle lvl-12, But I have no dragon/dragon..

Dragon Shout/Slayer buildings presume you already HAVE a dragon. What about players who does NOT have any dragons from the beginning? Am Level 13 castle already, But I don’t have any dragons. Other players with much lower level are talking about upgrading their dragons and a dragon altar. What is that? There is no dragon alter anywhere in my town.

Because it's an Just released update... I thought and assumed it was because I'm a beta tester but My base is lvl 25 .. When I logged on after last update it took me thru the beginning as if I had never played the game before.. So I went thru what their talking about.. They get a baby dragon and raise it thru an alter, then after lvl 20 you use the dragon buoldings.. I think it's something there trying to roll out with in the future to keep new ppl active .. Just ignore it.. As long as you can sound your battle horn and a dragon pops up, your ok.
